The AVF file contains three header lines annotated with "#". These lines should be used to identify the contents of the file. The header lines are followed by velocity records in card format. The datum is assumed to be the Seismic Datum set in your Project Preference. Velocities may be Stacking (RMS), Average or Interval.
The first line of each data record has five fields separated by white space. These fields are:
A location ID number (numeric value of your choice)
UTM X
UTM Y
Zero Depth (Datum)
Velocity at Zero Depth (Datum)
The second through "nth lines" of the record are composed of depth/velocity pairs.
The first record is followed by the second record and so forth to the end of file.
