boff - BSU program computes offset from source-receiver coordinates, loads result to header
boff [ -h | infile ]
Basic Seismic Utilities (BSU) computes source to receiver offset from coordinates found in the c_bsegy header. This offset is then stored in the header word reserved for offset (hd.idist). While the BSU programs never need this header value (after all, one can always compute it from the coordinate headers), it is necessary for some Seismic Unix (SU) programs (Colorado School of Mines). An example would be the Radon transform code in SU. Both SU and BSU are very similar in header design (derived from the old SEGY standard for tape). Where they differ most is in the multi-component and transducer/source polarization definitions stored in the optional header areas. In this case, the difference is more in the choices and decisions made during the setting of geometry (both BSU and SU define offset in the same place, but BSU geometry setting programs tend to ignore this header, since the BSU codes never look at it).

NOTE:
If invoked with no options, will prompt user for input
parameters.
EXAMPLE:
boff wave.seg
File wave.seg has the offset header value filled.
boffxxxx.seg
named according to convention (first 4char boff, the next 4char are the first 4char of the input file name, suffix .seg)
