Data are scaled to fit within an 8-bit unsigned byte value (pre-1977 data are scaled to a 6-bit unsigned byte value). See table GVENINDX.TAB for mapping of elevation range to byte values. Longitudes in the PDS label have been transformed into IAU 1985 coordinates from the original Goldstone coordinate system. The transformation is only approximate. The VICAR2 label has longitudes in the original Goldstone coordinate system, which are approximately 3.66 degrees smaller than the IAU 1985 values. For reference, see Jurgens, R. F., R. M.
