 "abstract": "Fourteen broadband magnetotelluric soundings on Liejun Wang's fifteen site traverse across the Adelaide Geosyncline, South Australia, running 284 km from the Stuart Shelf west of Port Augusta east to the western margin of the Murray Basin. Wang recorded five channels at each site with an EMI MT-1 and 200 m dipoles for his Flinders MSc, published as Wang and Chamalaun (1995).\nThe transfer functions served here are not Wang's own estimates. They are Ali Moradzadeh's independent reanalysis of Wang's raw time series, tabulated in Appendix II of his 1998 Flinders PhD thesis, and they reach this package through a 2021 WinGLink re-export of those tables. Every station carries the full impedance tensor over 39 or 41 periods from 0.0083 s to 833 s, and thirteen a tipper. No per period uncertainty survives; static shift is recorded, not applied. Depot Hill, the fifteenth site, has no tabulated values in any source held.",

  "changes_summary": "Fabricated variance and error blocks replaced by literal nan across 207 blocks and 8,097 cells. The 2008 WinGLink ACQDATE dropped. DATAID and SECTID named by the thesis site code in upper case, and LOC by the Table 3.2 site name in place of the delivery survey name. FILEBY written as AusMT, where the delivery leaves it an empty string. FILEDATE written as the date of this rendition, the delivery export date kept in each file. COUNTRY and STATE added, the delivery carrying neither. The EMEAS lines given the 200 m dipole geometry Wang and Chamalaun (1995) state, where every delivered EMEAS line carries zero geometry. LAT and LONG seconds rounded to two decimals, which moves ten of the fourteen by under a tenth of an arcsecond. PROSPECT carries the delivery value. The channel declarations state the frame of the numbers stored, HX 0 and HY 90 with dipoles running south to north and west to east, and the Moradzadeh Table 3.2 field sensor azimuths ride each file as recorded acquisition history. The impedance, the tipper and every block derived from either are the delivered bytes unaltered: 490 numeric blocks and 19,154 cells are identical to the delivery, maximum absolute difference 0, and so is every frequency grid. Each served file carries the sha256 of the delivered file it came from and the whole of its own HEAD difference against it.",
