ANGT: Angular Type
This record specifies the units of angular observations (ANGL, AZIM, DIR, GAZI, GVAN, GZAN, VANG, and ZANG). Note that latitudes and longitudes are always expressed in degrees, minutes, and seconds, and therefore this record does not affect the manner in which these values are expressed. The format of this record is:
Columns 002-005: ANGT
Columns 007-009: DMS (degrees, minutes, seconds), or GRD (grads)
Note that this record overrides the corresponding setting in the options file used for the network processing. It is provided for backward compatibility and is not normally used.
