NAME = GEO COLUMNS = 20 ROW_BYTES = 43 INTERCHANGE_FORMAT = BINARY PRIMARY_KEY = ( "SPACECRAFT_CLOCK_START_COUNT", "DETECTOR_NUMBER" ) DESCRIPTION = " The GEO table contains information about the sun/spacecraft/target geometry in a format that is easily searchable. These values are computed for every scan other than those used to calibrate the instrument. If a viewing vector does not intersect the target body (i.e., an atmospheric observation), then most of the geometry is calculated relative to the point on the viewing vector closest to the body (i.e., the tangent point). If the closest point lies behind the spacecraft, fill values are used."
