Acquired by Moombarriga Geoscience Pty Ltd for The University of Western Australia. The header dates of 19 served copies have been repaired; the delivered files are kept unaltered under provenance/as-delivered/ and every change is recorded in the served file itself.

This LICENSE.txt travels with the data files in this archive. The transfer functions were
distributed via the AusMT portal, which serves only openly licensed Australian magnetotelluric
releases; the licence above is the custodian's, set in the survey's survey.yaml. Reuse under the
terms of that licence (https://creativecommons.org/licenses/by/4.0/).

Changes were made: All 125 delivered files are served. 106 are byte identical to their archive member. 19 printed the Geotools placeholder ACQDATE=01/01/01: each had ACQDATE set to the date its own INFO block stamps on its recording start and FILEDATE rewritten from the month-first 12/02/20 to 2020-12-02 by _tools/repair_edi_header_dates.py, with a nine line record inserted after its INFO line, and its delivered bytes are kept under provenance/as-delivered/. No other byte was changed, proved file by file against provenance/as-delivered/, and no number, frame or gate verdict is altered.. AusMT serves derived renditions (canonical EMTF XML; MTH5 where available) generated from the deposited files; per-station conditioning notes are recorded in the machine-readable products.
