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: 30 of the 119 served files are byte identical to their member of 72959.zip. The other 89 printed the Geotools placeholder ACQDATE=01/01/01; each served copy carries ACQDATE set to the start date of its own recording, from the file's own RECORDING ID, and FILEDATE rewritten from the month-first 01/21/26 to 2026-01-21, by _tools/repair_edi_header_dates.py, with nine record lines inserted after >INFO. No other byte and no number is changed; the 89 delivered files are kept under provenance/as-delivered/.. 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.
