 "abstract": "A broadband magnetotelluric transect over the Ferguson Hill geothermal prospect, on Stuart Creek\npastoral lease about 90 km north of Roxby Downs, South Australia, acquired by Quantec Geoscience\nAustralia for Petratherm Limited on geothermal exploration licence GEL 158. Twenty-nine soundings\nwere recorded from 5 to 12 November 2007 at a nominal 500 m spacing along a 13.9 km line bearing\n029 degrees, to estimate the depth to crystalline basement and judge whether the cover insulates\na radiogenic heat source well enough for a geothermal resource. Recording was remote referenced\ntensor magnetotellurics on Quantec RT-130 loggers, 100 m dipoles and three induction coils per\nsite, referenced to a station 11 to 19 km east of the line. All 29 transfer\nfunctions carry impedance and tipper with variances at every period, 37 to 43 periods each,\nspanning 0.0034 to 1311 seconds with no absent value. They are served as stored, in the\nacquisition frame the files declare, 29 degrees east of north.",

All 29 files are byte-for-byte copies of the custodian's delivery, verified by sha256 against the delivery and recorded per file in provenance/served-files.json. The one thing this package adds is the file NAME: the delivery names its files by SARIG's own LineNo__StationNo sequence, and each served file is renamed to the DATAID the file itself prints, so the 29 stations publish as FH01 to FH29. No byte is edited, no frame is rotated and no correction of any kind is applied.",
