The steward counts walkers there before moving the group\r\ntowards the lantern rack.\r\nGroup limit\r\nA route group contains at most 14 walkers. A spare lantern does not create an extra place in the group.\r\nDeparture token\r\nThe steward carries a brass leaf token. The token identifies the group at the turntable crossing and stays\r\nwith the steward throughout the walk.\r\nLow-light hold\r\nIf the path light drops below the steward's marked line, walkers wait at the chalk arch. The steward\r\nrecords a low-light hold in the field booklet.\r\nRack check\r\nBefore departure, the steward checks the lantern hooks visually. Walkers take a lantern only after their\r\nnames have been checked against the meeting count.\r\nRoute practice\r\nThe group stops together when the steward gives the hand signal.

The length includes the loop around the display turntable.\r\nLantern return\r\nReturned lanterns go on rack Q5. A lantern with a loose hook is kept beside that rack rather than hung\r\non it.\r\nMarshal note\r\nThe marshal writes the brass leaf token number next to a release entry. The entry is separate from the\r\nwalker's names in the route steward's list.\r\nQuiet crossing\r\nThe group crosses the turntable in one continuous file.

The signoff is entered after the puppet has\r\nreturned from the orange bench.\r\n02 Packing layer\r\nReady cases are lined with green felt. The lining belongs to the case and remains in place when the\r\npuppet is lifted out.\r\n03 Ticket series\r\nThe current loan ticket series is CP-43. Staff copy the full series and number onto the case's return slip.\r\n04 Bench practice\r\nThe orange bench receives split wrist seams. Loose buttons use a separate repair note and do not\r\nautomatically receive the wrist-seam routing.\r\n05 Return list\r\nStaff compare the returned case with its printed list. A pencil tick on the return slip marks an item\r\nchecked, while a written note describes any observed gap.\r\n06 Ready-state boundary"

The\r\nfacilitator's control station is separate and does not\r\nadd a participant place.\r\nStarting track\r\nThe demonstration starts with track Flint.

The steward counts walkers there before moving the group\r\ntowards the lantern rack.\r\nGroup limit\r\nA route group contains at most 14 walkers. A spare lantern does not create an extra place in the group.\r\nDeparture token\r\nThe steward carries a brass leaf token. The token identifies the group at the turntable crossing and stays\r\nwith the steward throughout the walk.\r\nLow-light hold\r\nIf the path light drops below the steward's marked line, walkers wait at the chalk arch. The steward\r\nrecords a low-light hold in the field booklet.\r\nRack check\r\nBefore departure, the steward checks the lantern hooks visually. Walkers take a lantern only after their\r\nnames have been checked against the meeting count.\r\nRoute practice\r\nThe group stops together when the steward gives the hand signal.

The length includes the loop around the display turntable.\r\nLantern return\r\nReturned lanterns go on rack Q5. A lantern with a loose hook is kept beside that rack rather than hung\r\non it.\r\nMarshal note\r\nThe marshal writes the brass leaf token number next to a release entry.

The seed shapes are carved objects. This record concerns the demonstration sequence, not the\r\ncultivation of real plants.\r\nDisplay cycle\r\nThe demonstration dial completes one cycle in 32\r\nminutes. A guide points out the starting notch before\r\nreleasing the dial.\r\nOpening marker\r\nThe guide places the white pebble beside the\r\nstarting notch. Visitors can follow the pebble while\r\nthe dial begins to move.\r\nModel set\r\nThe public demonstration uses 12 wooden seed\r\nshapes. Shapes from the repair cabinet are not\r\nadded to this set during a demonstration.\r\nVisitor boundary\r\nVisitors watch from the curved floor line. Guides\r\npass a separate carved sample along the line while\r\nthe moving dial remains behind its cover.\r\nPaused stage\r\nDuring a fog pause, the dial is held at notch N3. The\r\nguide labels that pause in the demonstration log\r\nbefore giving an explanation.\r\nLog distinction\r\nA completed cycle and a paused cycle use separate\r\nlog entries. A guide does not combine two partial\r\ndemonstrations into one completed demonstration.\r\nFictional source record | Original corpus v15doc-03 | Page 1 of 3 Orrin Moss Seed Clock\r\nExhibit timing and cabinet notes\r\nControl cabinet\r\nThe cabinet contains the controls and the guide's stationary samples. Cabinet notes are checked when the\r\npublic exhibit changes from one guide to another. No setting here changes the size of the wooden seed\r\nshapes.\r\nPause marker\r\nThe fog-pause card is grey. It remains clipped\r\nbeside the control lever until the demonstration\r\nresumes.\r\nRestart control\r\nThe restart lever is marked Cedar. The guide\r\nreleases that lever after removing the pause card\r\nfrom the dial window.\r\nCabinet width\r\nThe sample cabinet is 84 cm wide. This dimension\r\ndescribes the cabinet alone, excluding the dial\r\nhousing beside it.\r\nGuide exchange\r\nOutgoing guides leave the stationary carved sample\r\non its felt square. Incoming guides check the sample\r\nand read the latest log entry before opening the\r\ncabinet.\r\nIncident envelope\r\nIncident notes are placed in a cream envelope.\r\nEach note identifies the affected demonstration\r\nwithout assigning a cause that the guide did not\r\nobserve.\r\nQuiet adjustment\r\nThe guide can straighten a sample's felt square\r\nbetween demonstrations. Adjustments inside the\r\ndial housing are recorded and handled by the exhibit\r\ntechnician."

Walkers take a lantern only after their\r\nnames have been checked against the meeting count.\r\nRoute practice\r\nThe group stops together when the steward gives the hand signal.

This desk record\r\ncovers the booth cards used during the autumn listening programme. A booth card is separate from a\r\nvisitor's entrance slip.\r\nEntry point\r\nVisitors with a booth card enter through the east reed gate. The western door serves the instrument\r\ncarrier and is not a public entrance.\r\nBooth format\r\nA normal booth session lasts 18 minutes. The room has nine fixed seats, with the centre seat kept clear\r\nwhile a microphone stand is moving.\r\nCard marking\r\nThe desk stamps returning visitors with a cobalt fern mark. The stamp shows repeat attendance; it does\r\nnot reserve a particular booth.\r\nReading the board\r\nThe route board lists booth names rather than people's names. Visitors are asked to read the board\r\nbefore lining up so that the queue can remain quiet.\r\nOverrun signal\r\nAn extension may be requested only after the amber chime. A booth volunteer records the request on\r\nthe back of the card before asking the supervisor.\r\nDesk habit\r\nStaff retain used cards until the next morning's count. Blank cards are kept in an unlabelled tray, away\r\nfrom the marked cards and the entrance slips.\r\nFictional source record | Original corpus v15doc-01 | Page 1 of 3 Ternwater Listening Pavilion\r\nBooth and visitor desk record\r\nListening-room operations\r\nThe booth volunteer handles the recorder and the supervisor handles changes to the daily sequence. The\r\nfollowing notes apply while the public programme is open. They do not describe the pavilion's closed\r\nrehearsal sessions.\r\nExtension decision\r\nMira Teal authorizes a session extension. The volunteer does not promise an extension before that\r\ndecision is written on the card.\r\nRecorder setting\r\nPublic booth recordings use a sample rate of 44.1 kHz. The desk does not change this setting for a\r\nshorter session.\r\nReel identity\r\nThe return reel is labelled TW-6. Its label is checked at the end of each session before the next visitors\r\nare admitted.\r\nDrink restriction\r\nOpen drinks must remain outside the listening room. Sealed bottles can stay inside visitors' bags but\r\ncannot be put on the recorder shelf.\r\nInterrupted take\r\nA dropped microphone stand ends the current take. The volunteer leaves the unfinished take marked as\r\ninterrupted and begins a fresh take when the room is settled.\r\nRoom reset"

The receiving team checks the carrier's studio tag before a block\r\nenters the store.\r\nRack allocation\r\nEach receiving rack holds 6 display blocks. A block under inspection keeps its rack place until the shift\r\nlead changes the entry.\r\nDelivery label\r\nThe delivery tag is sea-green. The tag travels with the receiving sheet while the block moves to its\r\nallocated rack.\r\nSculpture handoff\r\nAfter the contour check, finished sculptures move to the silver plinth.

A reading request\r\nidentifies a folder and a study table. These maps depict fictional places and are not intended for navigation\r\noutside the library.\r\nRequest window\r\nMap requests open at 09:40. Readers give the folder identifier at the cabinet counter before taking a\r\nseat.\r\nRequest limit\r\nOne reading request covers 4 map sheets. A folded sheet counts as one sheet even when its folds\r\ncreate several visible panels.\r\nFirst folder\r\nA reader's first request uses the Wren folder. Staff explain the folder tabs and the sheet labels with that\r\nexample.\r\nFlattening stage\r\nDuring the fold-settle stage, sheets rest under the ivory rail. Staff remove the rail before allowing the\r\nreader to turn a sheet.\r\nTable practice\r\nReaders use their own paper for notes. Nothing is written on a map sheet or placed inside a folder as a\r\nbookmark.\r\nIdentity record\r\nThe request keeps the sheet identifier along with the folder name. A reader's description of a town does\r\nnot replace either identifier.\r\nFictional source record | Original corpus v15doc-10 | Page 1 of 3 Juniper Ink Map Cabinet\r\nImaginary-map reading register\r\nSheet handling\r\nThe cabinet uses a short fold-settle stage before a sheet is read. The ivory rail is a handling aid and is not\r\npart of the map's depicted geography. The handler records the stage independently from the reader's notes.\r\nStage handler\r\nRae Noll manages the fold-settle stage. The handler checks the sheet after lifting the ivory rail.\r\nSheet width\r\nAn unfolded standard sheet is 46 cm wide. The figure describes the paper width, excluding its folder\r\ntabs.\r\nReading slip\r\nThe reading slip is coded JI-35. Staff copy the request identifier below the code before delivering a\r\nfolder.\r\nTurn sequence\r\nReaders turn one sheet at a time. A sheet returns to its labelled position in the folder before the next\r\nsheet is opened.\r\nFold note\r\nA split fold is recorded next to the sheet identifier. The handler does not call a sheet complete if a panel\r\nremains in a separate repair envelope.\r\nMap boundary\r\nThe maps' town names belong to the storytelling collection. No scale on a sheet certifies the existence of\r\na depicted town or the length of a real journey."

Readers consult\r\nsealed packets at the tables and return them to the counter. A packet is a reference object, not a dye\r\nrecipe.\r\nReader counter\r\nThe reader counter opens at 10:20. Earlier arrivals wait in the entrance room until the shutter has been\r\nraised.\r\nPacket limit\r\nA reader may borrow 3 swatch packets per visit. The counter records the packet identifiers together\r\nrather than making a separate visit for each one.\r\nFirst packet\r\nNew readers begin with the slate packet. Staff use it to demonstrate the label fold and the return\r\nenvelope before handing over other packets.\r\nReference table\r\nReaders unfold only the outer envelope at the table. The swatch remains inside its clear sleeve so that\r\nloose fibres do not settle on the tabletop.\r\nReview stage\r\nThe indigo tray is used during the dry-light review. Packets reach that stage after the counter has\r\nchecked the identifier against the visit entry.\r\nHandling note\r\nA pencil can be used on a reader's own notes.

It applies to the swatch collection\r\nnamed on the cover.\r\nReview holder\r\nThe dry-light review uses the indigo tray. Staff keep the tray level while reading the envelope identifier.\r\nClosure\r\nReturned envelopes are fastened with a copper paper clip. Tape is not part of the standard envelope\r\nclosure.\r\nEnvelope count\r\nEach reference packet contains 7 swatches. This count includes the narrow comparison strip next to the\r\nmain swatches.\r\nColour notes\r\nStaff copy the packet's colour names exactly into the ledger. They do not rename a colour to match the\r\nreader's description or a sample brought from home.\r\nRelease tag\r\nA reviewed packet receives tag SL-28.

Visitors book a short bench session. The record concerns that rig and does not describe\r\nthe fitting or road use of a bicycle bell.\r\n01 Booking duration\r\nA bench booking lasts 24 minutes. The duration includes the visitor's first sound comparison and the\r\nend-of-session return check.\r\n02 Rig position\r\nThe demonstration rig stands on platform J1. Visitors remain beside the painted bench line while the\r\nhost changes a bell.\r\n03 Comparison pair\r\nThe opening comparison uses the Alder and Rowan bells. The names distinguish the studio's\r\ndemonstration objects rather than tree materials used in manufacture.\r\n04 Muted stage\r\nDuring the felt-damped test, the host places a burgundy pad under the bell. The pad is removed before\r\nthe free-ring comparison begins.\r\n05 Session card\r\nThe host writes the booking identifier on a white session card. A visitor can describe a preferred sound\r\non that card without renaming the demonstration objects.\r\n06 Rig boundary\r\nOnly the host changes the bell on the rig. The visitor operates the indicated striker after the host has\r\nchecked the bell's position.\r\nFictional source record | Original corpus v15doc-09 | Page 1 of 3 Larch Ribbon Bicycle Bell Studio\r\nDemonstration bench session record\r\nTesting and return check\r\nThe studio compares the two named sounds using the same rig. The felt-damped test has its own pad and\r\nis recorded separately from the free-ring comparison. A preferred sound is a visitor's observation, not a\r\nrating assigned to the whole bell range.\r\n01 Test host\r\nEli Dorr hosts the felt-damped test. The host records that stage before removing the burgundy pad.\r\n02 Striker weight\r\nThe demonstration striker weighs 38 g. This weight describes the rig's striker and excludes the handle\r\nassembly.\r\n03 Check form\r\nThe return check uses form LR-61. The booking identifier is copied from the white session card.\r\n04 Sound description\r\nVisitors can use their own words for the sounds. The host leaves those words as observations and does\r\nnot convert them into a measurement the visitor did not make.\r\n05 Object sequence\r\nThe host returns Alder before Rowan to their marked hooks. Both bells are checked before the next\r\nbooking begins.\r\n06 Pad distinction"

Participants\r\ngather at the sound-table sign before the facilitator\r\nchecks the session list.\r\nTable capacity\r\nThe sound table has 8 participant stations. The\r\nfacilitator's control station is separate and does not\r\nadd a participant place.\r\nStarting track\r\nThe demonstration starts with track Flint. The\r\nfacilitator plays it once before inviting participants to\r\nuse their station controls.\r\nMuted stage\r\nDuring the silent preview, participants read the violet\r\nstrip. The facilitator keeps the table's audio muted\r\nfor that stage.\r\nStation cards\r\nStation cards carry letters rather than names.\r\nParticipants use the same letter in their worksheet\r\nso that the facilitator can identify an observation\r\nwithout calling a name aloud.\r\nExample boundary\r\nThe track labels are names for demonstration\r\nmaterial. They do not identify meteorites, forecast a\r\nsky event or claim that the table captured a\r\nparticular historical observation.\r\nFictional source record | Original corpus v15doc-07 | Page 1 of 3 Bramble Observatory Meteor Echo\r\nWorkshop sound-table instructions\r\nPreview and playback\r\nThe silent preview shows the participant the notation before playback. The violet strip is a printed aid and is\r\nnot a volume control. Playback is a separate workshop stage with its own instruction from the facilitator.\r\nPlayback cue\r\nPlayback begins when the facilitator raises the\r\nsquare card. The cue follows the silent preview and\r\nis visible from each participant station.\r\nTone spacing\r\nThe demonstration tone spacing is 240 Hz. This\r\nvalue labels the table example and is not a property\r\nassigned to all meteor echoes.\r\nWorksheet code\r\nThe workshop worksheet is coded BM-72.\r\nParticipants write their station letter beneath the\r\ncode.\r\nPrinted aid\r\nThe violet strip remains on the table during\r\nplayback. Participants can compare its marks with\r\nthe sounds, but they do not edit the printed strip.\r\nReplay request\r\nA participant can raise a station card to request a\r\nreplay.

It tracks display blocks and\r\ncompleted sculptures inside a cold store. The figures describe the studio's fictional handling plan and do not\r\nconstitute refrigeration advice.\r\nReceiving bay\r\nDisplay blocks arrive through bay H2. The receiving team checks the carrier's studio tag before a block\r\nenters the store.\r\nRack allocation\r\nEach receiving rack holds 6 display blocks. A block under inspection keeps its rack place until the shift\r\nlead changes the entry.\r\nDelivery label\r\nThe delivery tag is sea-green. The tag travels with the receiving sheet while the block moves to its\r\nallocated rack.\r\nSculpture handoff\r\nAfter the contour check, finished sculptures move to the silver plinth. A sculpture with an unfinished\r\ncontour check remains at its work position.\r\nCarrier distinction\r\nThe carrier's receipt is retained separately from the studio tag. The receipt records delivery, while the\r\nstudio tag identifies the object within the shift ledger.\r\nShift continuity\r\nAn incoming shift reads the receiving entries before moving blocks. The ledger does not permit a rack\r\nposition to be erased merely because a block is temporarily elsewhere.\r\nFictional source record | Original corpus v15doc-06 | Page 1 of 3 Vela Harbor Ice Ledger\r\nSculpture cold-store shift record\r\nStore positions and review\r\nThe cold-store review tracks the physical stage reached by each sculpture.

These are demonstration tracks rather than observations of real meteors. The workshop's\r\ninstruments are described only for this activity.\r\nEntry session\r\nThe first workshop begins at 11:45. Participants\r\ngather at the sound-table sign before the facilitator\r\nchecks the session list.\r\nTable capacity\r\nThe sound table has 8 participant stations. The\r\nfacilitator's control station is separate and does not\r\nadd a participant place.\r\nStarting track\r\nThe demonstration starts with track Flint. The\r\nfacilitator plays it once before inviting participants to\r\nuse their station controls.\r\nMuted stage\r\nDuring the silent preview, participants read the violet\r\nstrip. The facilitator keeps the table's audio muted\r\nfor that stage.\r\nStation cards\r\nStation cards carry letters rather than names.\r\nParticipants use the same letter in their worksheet\r\nso that the facilitator can identify an observation\r\nwithout calling a name aloud.\r\nExample boundary\r\nThe track labels are names for demonstration\r\nmaterial.

The violet strip is a printed aid and is\r\nnot a volume control. Playback is a separate workshop stage with its own instruction from the facilitator.\r\nPlayback cue\r\nPlayback begins when the facilitator raises the\r\nsquare card. The cue follows the silent preview and\r\nis visible from each participant station.\r\nTone spacing\r\nThe demonstration tone spacing is 240 Hz. This\r\nvalue labels the table example and is not a property\r\nassigned to all meteor echoes.\r\nWorksheet code\r\nThe workshop worksheet is coded BM-72.\r\nParticipants write their station letter beneath the\r\ncode.\r\nPrinted aid\r\nThe violet strip remains on the table during\r\nplayback. Participants can compare its marks with\r\nthe sounds, but they do not edit the printed strip.\r\nReplay request\r\nA participant can raise a station card to request a\r\nreplay.

Stewards use\r\nthis booklet to organize a short evening route. It does not grant access to any working quarry or certify\r\noutdoor equipment.\r\nMeeting place\r\nThe group meets at the blue crane mural. The steward counts walkers there before moving the group\r\ntowards the lantern rack.\r\nGroup limit\r\nA route group contains at most 14 walkers. A spare lantern does not create an extra place in the group.\r\nDeparture token\r\nThe steward carries a brass leaf token. The token identifies the group at the turntable crossing and stays\r\nwith the steward throughout the walk.\r\nLow-light hold\r\nIf the path light drops below the steward's marked line, walkers wait at the chalk arch. The steward\r\nrecords a low-light hold in the field booklet.\r\nRack check\r\nBefore departure, the steward checks the lantern hooks visually. Walkers take a lantern only after their\r\nnames have been checked against the meeting count.\r\nRoute practice\r\nThe group stops together when the steward gives the hand signal. A walker who wants to leave tells the\r\nsteward at the next stop so that the count can be updated.\r\nFictional source record | Original corpus v15doc-04 | Page 1 of 3 Fenn Quarry Lantern Route\r\nRoute steward field booklet\r\nCrossing and route holds\r\nThe crossing marshal remains at the turntable while the route steward moves with the group. Route holds\r\nare entered in the booklet independently of lantern faults. These entries make clear where the group is\r\nwaiting and who can release it.\r\nRelease authority\r\nThe crossing marshal releases a low-light hold. The route steward waits for that release before moving\r\nwalkers away from the chalk arch.\r\nRoute length\r\nThe marked route is 1.8 km long. The length includes the loop around the display turntable.\r\nLantern return\r\nReturned lanterns go on rack Q5. A lantern with a loose hook is kept beside that rack rather than hung\r\non it.\r\nMarshal note\r\nThe marshal writes the brass leaf token number next to a release entry. The entry is separate from the\r\nwalker's names in the route steward's list.\r\nQuiet crossing\r\nThe group crosses the turntable in one continuous file. The steward waits until the last walker has\r\nreached the far marker before starting the next count.\r\nFault handling"

These are demonstration tracks rather than observations of real meteors. The workshop's\r\ninstruments are described only for this activity.\r\nEntry session\r\nThe first workshop begins at 11:45. Participants\r\ngather at the sound-table sign before the facilitator\r\nchecks the session list.\r\nTable capacity\r\nThe sound table has 8 participant stations. The\r\nfacilitator's control station is separate and does not\r\nadd a participant place.\r\nStarting track\r\nThe demonstration starts with track Flint. The\r\nfacilitator plays it once before inviting participants to\r\nuse their station controls.\r\nMuted stage\r\nDuring the silent preview, participants read the violet\r\nstrip. The facilitator keeps the table's audio muted\r\nfor that stage.\r\nStation cards\r\nStation cards carry letters rather than names.\r\nParticipants use the same letter in their worksheet\r\nso that the facilitator can identify an observation\r\nwithout calling a name aloud.\r\nExample boundary\r\nThe track labels are names for demonstration\r\nmaterial. They do not identify meteorites, forecast a\r\nsky event or claim that the table captured a\r\nparticular historical observation.\r\nFictional source record | Original corpus v15doc-07 | Page 1 of 3 Bramble Observatory Meteor Echo\r\nWorkshop sound-table instructions\r\nPreview and playback\r\nThe silent preview shows the participant the notation before playback. The violet strip is a printed aid and is\r\nnot a volume control. Playback is a separate workshop stage with its own instruction from the facilitator.\r\nPlayback cue\r\nPlayback begins when the facilitator raises the\r\nsquare card. The cue follows the silent preview and\r\nis visible from each participant station.\r\nTone spacing\r\nThe demonstration tone spacing is 240 Hz. This\r\nvalue labels the table example and is not a property\r\nassigned to all meteor echoes.\r\nWorksheet code\r\nThe workshop worksheet is coded BM-72.\r\nParticipants write their station letter beneath the\r\ncode.\r\nPrinted aid\r\nThe violet strip remains on the table during\r\nplayback. Participants can compare its marks with\r\nthe sounds, but they do not edit the printed strip.\r\nReplay request\r\nA participant can raise a station card to request a\r\nreplay.

This desk record\r\ncovers the booth cards used during the autumn listening programme. A booth card is separate from a\r\nvisitor's entrance slip.\r\nEntry point\r\nVisitors with a booth card enter through the east reed gate. The western door serves the instrument\r\ncarrier and is not a public entrance.\r\nBooth format\r\nA normal booth session lasts 18 minutes. The room has nine fixed seats, with the centre seat kept clear\r\nwhile a microphone stand is moving.\r\nCard marking\r\nThe desk stamps returning visitors with a cobalt fern mark. The stamp shows repeat attendance; it does\r\nnot reserve a particular booth.\r\nReading the board\r\nThe route board lists booth names rather than people's names. Visitors are asked to read the board\r\nbefore lining up so that the queue can remain quiet.\r\nOverrun signal\r\nAn extension may be requested only after the amber chime. A booth volunteer records the request on\r\nthe back of the card before asking the supervisor.\r\nDesk habit\r\nStaff retain used cards until the next morning's count. Blank cards are kept in an unlabelled tray, away\r\nfrom the marked cards and the entrance slips.\r\nFictional source record | Original corpus v15doc-01 | Page 1 of 3 Ternwater Listening Pavilion\r\nBooth and visitor desk record\r\nListening-room operations\r\nThe booth volunteer handles the recorder and the supervisor handles changes to the daily sequence. The\r\nfollowing notes apply while the public programme is open. They do not describe the pavilion's closed\r\nrehearsal sessions.\r\nExtension decision\r\nMira Teal authorizes a session extension. The volunteer does not promise an extension before that\r\ndecision is written on the card.\r\nRecorder setting\r\nPublic booth recordings use a sample rate of 44.1 kHz. The desk does not change this setting for a\r\nshorter session.\r\nReel identity\r\nThe return reel is labelled TW-6. Its label is checked at the end of each session before the next visitors\r\nare admitted.\r\nDrink restriction\r\nOpen drinks must remain outside the listening room. Sealed bottles can stay inside visitors' bags but\r\ncannot be put on the recorder shelf.\r\nInterrupted take\r\nA dropped microphone stand ends the current take. The volunteer leaves the unfinished take marked as\r\ninterrupted and begins a fresh take when the room is settled.\r\nRoom reset"

The facilitator keeps the table's audio muted\r\nfor that stage.\r\nStation cards\r\nStation cards carry letters rather than names.\r\nParticipants use the same letter in their worksheet\r\nso that the facilitator can identify an observation\r\nwithout calling a name aloud.\r\nExample boundary\r\nThe track labels are names for demonstration\r\nmaterial. They do not identify meteorites, forecast a\r\nsky event or claim that the table captured a\r\nparticular historical observation.\r\nFictional source record | Original corpus v15doc-07 | Page 1 of 3 Bramble Observatory Meteor Echo\r\nWorkshop sound-table instructions\r\nPreview and playback\r\nThe silent preview shows the participant the notation before playback. The violet strip is a printed aid and is\r\nnot a volume control. Playback is a separate workshop stage with its own instruction from the facilitator.\r\nPlayback cue\r\nPlayback begins when the facilitator raises the\r\nsquare card. The cue follows the silent preview and\r\nis visible from each participant station.\r\nTone spacing\r\nThe demonstration tone spacing is 240 Hz. This\r\nvalue labels the table example and is not a property\r\nassigned to all meteor echoes.\r\nWorksheet code\r\nThe workshop worksheet is coded BM-72.\r\nParticipants write their station letter beneath the\r\ncode.\r\nPrinted aid\r\nThe violet strip remains on the table during\r\nplayback. Participants can compare its marks with\r\nthe sounds, but they do not edit the printed strip.\r\nReplay request\r\nA participant can raise a station card to request a\r\nreplay. The facilitator notes the request before"
