Some versions of these codes have been put on the J drive under "EECMS/CIRA/Operations/Maps&Locations/MWA", but these are clearly copies of Randall's original code that he had no idea were there, so they should not be considered definitiveauthoritative. 

History

32T

Tile locations for the prototype 32T array were surveyed sometime in 2008. The most definitive document available for the locations is "32T_Reordered_Tile_Corner_Coordinates.xls" in the Curtin J drive under .../MWA/Phase0-32T/Construction. It isn't known if this is truly the original, or derived from something else. This includes the location of the marker rock outside the MWA donga (these match exactly the numbers for the MWA centre above). The spreadsheet doesn't say who did the surveying or what the coordinate system was, but putting the easting and northing values into a Geoscience Australia Converter gives the exact public coordinates for the WGS84 and GRS80 ellipsoids, so it is reasonable to assume WGS84 was used.

The original survey data spreadsheet for the tiles appears to be on the J drive as in .../Shared/EECMS/CIRA/Operations/MWA/Phase1-128T/Locations/

The file "128_Surveyed_Locations.xls" appears to be the original from HTD, the surveying company. It does not say so explicitly in this spreadsheet, but the surveyed points were the south-west corners of the tiles, so the true centre of the tile is +2.5m north and east of that point. The surveyed locations of the receivers (or receiver pads) is in a file "ASCON Rx Locations.xls" in the same directory.
