 "abstract": "Twenty one broadband magnetotelluric stations recorded near Broken Hill, New South Wales, by the University of Sydney between 18 June and 3 July 2024, over a footprint of roughly 20 by 18 km covering the Broken Hill Pb-Zn-Ag deposit and the Broken Hill Group. Acquisition used Phoenix MTU-5C receivers with MTC-155 and MTC-185 induction coils and 100 m electric dipoles, remote-referenced, each station recording between 9 and 26 hours. Processing was EMpower v2.22.0.1 and the files were written by MTpy. Served periods run 1.0e-04 s to 2913 s, 84 to 100 periods per station, 2006 periods in total. The tensors are stored in geomagnetic north. The declination the files state is 9 degrees at fourteen stations and 18 degrees at seven, so a user rotating to geographic must choose; AusMT serves them as stored and rotates nothing.",
