 "abstract": "A broadband magnetotelluric transect across the Curnamona Province of eastern South Australia:\n18 soundings on one east west line, 163.5 km end to end between 139.218 and 140.945 degrees east\nnear latitude 31.7 south, at a mean station spacing of 9.9 km. The University of Adelaide\nacquired it with the South Australian department and Geoscience Australia, and the state's own\nsurvey record, SA Geodata electrical survey 52, gives the field window as 23 April to 7 May 2010.\nThe line extends the Gawler Curnamona Link of September 2009 eastward, its first station standing\n11.3 km beyond that survey's last. Transfer functions were exported from WinGLink in 2019. Every\nstation carries impedance with variances on 43 to 54 frequencies, a median of 52, from 100 Hz to\n0.0005 Hz; 15 of the 18 also carry a tipper. Released open file by the Geological Survey of South\nAustralia. AusMT serves all 18 byte for byte in the frame they declare.",

The 18 served EDIs are byte-for-byte copies of the custodian's delivery, verified by sha256 against both the delivery and the named upload set. The only change is the filename: SARIG delivers each sounding as LineNo__StationNo_<n>.edi, which is a database sequence rather than a station identity, and each file is copied to the name of its own DATAID. The custodian's own filename and the digest of its bytes are recorded per file in provenance/served-files.json. No frame is rotated, no coordinate is repaired, no header is corrected and no value is inferred.",
