 Gravity corrections were calculated using station locations based on the NAD27 CRS and the NVD29 vertical
 datum. Absoluted gravity measurements were calculated using the 1967 formula based on the IGSN71 datum. For
 consistency with the SRTM DEM gravity station locations were transformed into lat,lon and UTM coordinates
 based on the WGS84 CRS and the WGS84 ellipsoid.
