Seismic Unix
While BSU is completely independent of Seismic Unix (SU), it is highly
compatible with it, but only if SU has been compiled without XDR. The XDR option in SU originated around 1997 and is essentially a big endian byte order with IEEE encoding of floats.
See section 6.6.4 for more on this topic. I use both, often plotting
BSU results with SU software (see the bash scripts xPlot-su and
psPlot-su in the
BSU scripts directory). The structure of the binary data formats are
the same (240 byte trace header followed by 4 byte floating point
data). The number of samples and sample interval headers are identical.
The header formats do differ in some important ways (BSEGY has definitions
for source and receiver polarizations). In short, SU has a program,
segyclean, which permits SU to read BSU files, should a difficulty
be encountered. To download SU, visit the Center for Wave Propagation
at Colorado School of Mines, http://www.cwp.mines.edu/cwpcodes.
