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: The served set is 666 of the 669 delivered soundings: IEB0562A, IEB1650A and IEB1813A are withheld under owner ruling 2026-09-19 (the YMB057 precedent) because each declares a frame its own header contradicts, and their delivered files are kept unaltered under provenance/as-delivered/ with the measurements and the ruling recorded in provenance/served-files.json. Four of the 666 served files carry a header date repair and no other change: where ACQDATE printed the exporter placeholder 01/01/01 it was SET from Appendix 1 of the contractor's report delivered in the same archive, IEB0955A and IEB0956A to 2014-08-13 and IEB0961A and IEB0962A to 2014-08-15, and FILEDATE was rewritten from 09/23/14 into 2014-09-23. Nothing was blanked and no number in any file was touched. The delivered bytes of those four are kept under provenance/as-delivered/ beside the three withheld files, seven in all. The other 662 served files are byte identical to their archive member.. 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.
