Liejun Wang acquired this station and published his own interpretation of it; the transfer functions served here are Ali Moradzadeh s independent reprocessing of Wang s raw series, tabulated in the appendix named below. Wang s own estimates are tabulated in no source AusMT holds\nausmt.origin.acquisition_paper=Wang, L.J. and Chamalaun, F.H. (1995). A magnetotelluric traverse across the Adelaide geosyncline.

Alma MMS 994689201771.\nausmt.origin.values_from=Appendix II, Table of impedance tensor and tipper values, thesis pages 265 to 301; this station at thesis page 292\nausmt.origin.appendix_frame=Appendix II tabulates the UNROTATED impedance tensor, which is in the field sensor directions, together with the tipper, which its own column glossary at thesis page 265 gives in the northward and eastward directions with Angle r referenced to geographic north; thesis page 66 names the appendix and carries the word unrotated on the impedance tensor alone\nausmt.origin.appendix_preamble=Appendix II opens at thesis page 265 with a sentence that reads against that: \"The elements of the MT impedance tensor and tipper function are given in the field sensors directions.\" The same page answers it. The column glossary two paragraphs later is specific to the tipper columns and places them in geographic axes, and the sensor caveat standing between the two prescribes ONE remedy, a sign change on the off-diagonal elements of the IMPEDANCE tensor, and prescribes nothing for the tipper and no rotation for anything\nausmt.origin.station_table=Table 3.2, thesis pages 54 to 55; this station at page 55\nausmt.origin.export=WinGLink EDI 1.0.22, re-exported 27 July 2021 by a third party whom no byte of the delivery names\nausmt.origin.export_file=pin.edi\nausmt.origin.export_sha256=1b55cd2a9faacdd76d03cd5e38e1c9b76b4fd6005d5fc0e59027f515fc8d24ae\nausmt.origin.export_transform=the export applied the Table 3.2 sensor projection to the impedance and then NEGATED THE WHOLE TENSOR, and left the tipper exactly as Appendix II prints it\nausmt.origin.export_transform_fit=over the 312 impedance cells of this station the map -(Pe^-1 Z Ph) carries the printed table onto the impedance served here exactly, cell for cell. Pe and Ph are the matrices whose rows are the Table 3.2 sensor unit vectors, and a cell relative difference is taken against the larger of the two magnitudes\nausmt.origin.export_transform_exceeds_the_thesis=Appendix II prescribes a sign change on the OFF-DIAGONAL elements at the sites Table 3.2 marks; the export changed the sign of all four elements at every site, including the four of these fourteen whose Table 3.2 row declares no reversed sensor at all\nausmt.origin.sign_gate=the printed table carried into geographic axes without that negation FAILS the AusMT quadrant gate at this station, medians arg Zxy -154.8 and arg Zyx 21.99 degrees; with the negation it passes at 25.2 and -159.73, which is what the file serves\nausmt.origin.sign_gate_limit=the served sign rests on that quadrant test and on the export agreeing with it, not on a statement by either author; the two readings are 180 degrees apart and only the raw series or an author separates them\nausmt.origin.magnetic_half_untestable=Table 3.2 gives this station a cardinal magnetic pair, so Ph is exactly the identity and the electric-half-only fault found elsewhere in this export cannot be distinguished here\nausmt.origin.transposition_excluded=a free real four by four map fitted from the printed values to the exported ones is of Kronecker form on the direct tensor, rank ratio 8.810e-16, which every physical frame change must be; no transposed reading is competitive\nausmt.origin.raw_time_series=not held by AusMT; whereabouts not known\nausmt.station.code=PIN\nausmt.station.name=Pine Vale\nausmt.station.name_in_the_thesis_prose=Pine Valley; Table 3.2 and this file carry Pine Vale, and the paper names the place at all\nausmt.station.latitude_deg=-33.324167\nausmt.station.longitude_deg=140.193056\nausmt.station.position_source=Moradzadeh (1998) Table 3.2, which is the only source that gives a position for this station; Wang and Chamalaun (1995) print no site table and no coordinate, only a map and an along profile distance axis\nausmt.station.position_agreement_m=0.56, the delivered position against the Table 3.2 position\nausmt.station.elevation_m=96\nausmt.station.elevation_source=introduced by the 2021 export; Table 3.2 prints no elevation column and no source for it is held\nausmt.station.profile=the single east to west traverse across the Adelaide Geosyncline, which Moradzadeh (1998) calls profile 1\nausmt.station.n_periods=39\nausmt.station.band_hz=120.1170 to 0.0012\nausmt.station.band_s=0.00833 to 833.33\nausmt.station.frequency_grid=matches the printed grid period for period, maximum absolute disagreement 1.000e-05 Hz and maximum relative disagreement 4.167e-07, which is the rounding of the frequency column the thesis prints\nausmt.station.coordinate_datum=not stated by any source; the thesis Table 3.2 predates routine datum reporting, so AGD66 or AGD84 cannot be excluded\nausmt.dates.acquisition_thesis=1993, the survey date column of Table 3.2\nausmt.dates.acquisition_paper=November 1992, the only acquisition date printed in Wang and Chamalaun (1995), at journal page 540, by the people who did the fieldwork\nausmt.dates.acquisition_unresolved=THE TWO SOURCES DISAGREE and AusMT has not settled them. The paper is the acquirer s own account and the thesis is the reprocessor s; neither states a month for the other s figure, and no station level date exists in either. The package is named for the thesis year\nausmt.dates.acqdate_dropped=the export stamped ACQDATE=12/01/08 into every file; that is a WinGLink project date from 2008 and is not an acquisition date, so it is not carried\nausmt.dates.export_filedate=07/27/21\nausmt.header.changed_fields=DATAID \"pin\" to \"PIN\"; FILEBY \"\" to \"AusMT\"; FILEDATE 07/27/21 to 2026-08-30; LOC \"Flinders Ranges\" to \"Pine Vale\"; COUNTRY absent, written Australia; STATE absent, written \"South Australia\"; ACQDATE 12/01/08 dropped\nausmt.header.changed_fields_scope=that list is the whole of the HEAD difference between this file and the delivered one, computed field by field when this file was written. PROSPECT carries the delivery value; the LAT and LONG change is the rounding of the seconds to two decimals, under a tenth of an arcsecond wherever it is not zero\nausmt.uncertainty.served=none\nausmt.uncertainty.blocks_nulled=ZXX.VAR ZXY.VAR ZYX.VAR ZYY.VAR RHOXY.ERR RHOYX.ERR RHOXX.ERR RHOYY.ERR PHSXY.ERR PHSYX.ERR PHSXX.ERR PHSYY.ERR TXVAR.EXP TYVAR.EXP TIPMAG.VAR\nausmt.uncertainty.cells_nulled=585\nausmt.uncertainty.reason=every source variance cell equals one twentieth of the matching real part and every error cell is a closed form function of that, so none of them is a measurement; neither the thesis nor the paper prints a per frequency uncertainty anywhere, the paper plotting one sigma bars it tabulates nowhere\nausmt.uncertainty.written_as=literal nan, an absent value a reader cannot mistake for a measurement; the EDI EMPTY sentinel and an absent block both read back as 0.0, which is an infinite weight in an inversion\nausmt.uncertainty.variance_cells_checked=156/156 impedance and 78/78 tipper variance cells of this station equal one twentieth of the matching real part\nausmt.uncertainty.site_average_source=Moradzadeh (1998) Table 5.1, average error in per cent of apparent resistivity and phase for each site, thesis page 112\nausmt.uncertainty.rho_xy_mean_pct=2.1\nausmt.uncertainty.phase_xy_mean_pct=3.69\nausmt.uncertainty.rho_yx_mean_pct=2.69\nausmt.uncertainty.phase_yx_mean_pct=2.71\nausmt.uncertainty.site_average_scope=one arithmetic average over all frequencies per station per mode, off diagonals only; no entry exists for ZXX, ZYY or the tipper\nausmt.uncertainty.phase_unit_unresolved=the thesis captions both columns as per cent and never states what the phase column is a percentage of\nausmt.static_shift.applied=no\nausmt.static_shift.source=Moradzadeh (1998) Table 5.2, logarithm values of the shift for each site and polarisation mode, thesis page 122; Wang and Chamalaun (1995) do not use the words static shift anywhere\nausmt.static_shift.log10_tm=0.06\nausmt.static_shift.log10_te=0.03\nausmt.static_shift.to_apply=subtract the log10 value from log10 of the served apparent resistivity; the thesis states that a negative shift means the measured resistivity was depressed below its undistorted value\nausmt.static_shift.base_is_an_inference=THE THESIS STATES NO BASE. Table 5.2 is captioned Logarithm values of the shift for each site and polarisation mode and names no base anywhere; the magnitudes are consistent with base 10, which is what the two key names above and the instruction for applying them assert. Renaming those keys is an owner ruling pending on this package and on moradzadeh-mt-1996-97 together\nausmt.frame.impedance=served as the 2021 export wrote it; ZROT and RHOROT are zero at every frequency and the impedance is in the geographic frame, x north and y east\nausmt.frame.time_dependence=exp(+i omega t); phase is atan2(imaginary, real)\nausmt.channels.declared_hx_deg=0\nausmt.channels.declared_hy_deg=90\nausmt.channels.declared_azimuths_are=the frame of the numbers STORED, which is the geographic frame ZROT and TROT declare; the field azimuths below are history\nausmt.channels.sensor_ex_deg=0\nausmt.channels.sensor_ey_deg=270\nausmt.channels.sensor_hx_deg=0\nausmt.channels.sensor_hy_deg=90\nausmt.channels.sensor_azimuth_source=Moradzadeh (1998) Table 3.2, thesis pages 54 to 55\nausmt.channels.sensor_azimuth_north_unresolved=WHAT NORTH THOSE FIELD AZIMUTHS ARE REFERENCED TO IS NOT STATED. Wang and Chamalaun (1995) at journal page 540 say the telluric system was aligned in MAGNETIC north south and east west directions where local conditions permitted; neither the paper nor Table 3.2 states a declination, states whether the recorded azimuths were corrected to true north, or gives a value for either. Local declination in the early 1990s is of order 7 to 8 degrees east, larger than most of the Table 3.2 departures from cardinal\nausmt.channels.dipole_length_m=200\nausmt.channels.dipole_length_source=Wang and Chamalaun (1995) journal page 540, the bipole lengths were 200 meters, and that is the ONLY witness for this survey. Thesis page 52 gives 200 m dipoles too but is section 3.3.2.2 Sensors installation, which is Moradzadeh s account of his OWN 1996-97 field procedure and not of Wang s, so it is not cited for this station\nausmt.channels.dipole_geometry_written_by_ausmt=the EMEAS lines below carry X -100 to X2 100 and Y -100 to Y2 100, a 200 m dipole centred on the site, written from the 200 m the paper states; every delivered EMEAS line carries zero geometry and no azimuth at all\nausmt.channels.rx_ry_note=the DEFINEMEAS block repeats HX and HY as RX and RY; that is a WinGLink artefact and NOT a remote reference, of which this survey had none\nausmt.tipper.served=yes\nausmt.tipper.frame=geographic, x north and y east\nausmt.tipper.transformed_by_ausmt=no; the served values are the delivered values, which are Appendix II as printed\nausmt.tipper.frame_source=the Appendix II column glossary, thesis page 265: Txr and Tyr are the real elements of the tipper function in the x (northward) and y (eastward) directions, and Angle r is the azimuth of the reversed real induction arrow with respect to geographic north\nausmt.tipper.frame_preamble=the page those columns are defined on opens with the sentence that reads the other way: \"The elements of the MT impedance tensor and tipper function are given in the field sensors directions.\"\nausmt.tipper.frame_preamble_answered=the glossary is specific to these columns and the preamble is general; the sensor caveat between them prescribes one remedy, a sign change on the off-diagonal elements of the IMPEDANCE tensor, and prescribes nothing for the tipper; and the arithmetic settles it, because arg(-Tyr, -Txr) of the served components reproduces the printed Angle r at all thirteen tipper stations to better than 0.05 degrees, where a tipper read in the field sensor frame would move Angle r at JAC by 2.0 degrees and at SUG by 3.0 degrees and leave the other eleven untouched, their magnetic pairs being cardinal\nausmt.tipper.delivered_equals_printed=the delivered tipper is the printed tipper bit for bit at this station, maximum absolute difference 0.0e+00 over its four components and 0 cells disagreeing\nausmt.tipper.frame_crosscheck=arg(-Tyr, -Txr) computed from the served components reproduces the printed Angle r at every period of this station, maximum deviation 0.0492 degrees and median 0.0240 against a printed precision of 0.1; the printed Rr agrees with hypot(Txr, Tyr) to 0.0050\nausmt.tipper.derived_blocks=TIPMAG TIPPHS TSTRIKE TSKEW TELLIP INDMAGR.EXP INDMAGI.EXP INDANGR.EXP INDANGI.EXP\nausmt.tipper.derived_blocks_reason=frame dependent, and served as delivered because the tipper they were computed from is the tipper served here; TIPMAG.VAR is nulled with the other variance blocks\nausmt.tipper.hz_polarity=unestablished for the whole survey; Table 3.2 carries no Hz column, so a global tipper sign error cannot be excluded at any station\nausmt.caution.uncorrected=served as the custodian processed it: no static shift correction, no error floor, no reprocessing\nausmt.caution.wangs_own_estimates=not served by this package and not held: Wang s 1994 MSc is the only source that would carry them, and AusMT does not hold it\nausmt.caution.plotted_frame_of_the_paper=every response curve in Wang and Chamalaun (1995) is rotated into a north south regional strike, which is a third frame distinct from the field sensor frame Appendix II prints and from the geographic frame this file serves; a reader comparing this file against the paper figures is comparing two frames"
