bsrt - BSU program sorts traces by offset (C-Language Version)
bsrt [ -h | infile | isort ]
Basic Seismic Utilities (BSU) computes the source to receiver offset from the headers, and then sorts the traces by offset. One may do an upsort (increasing offset) or a down sort (decreasing offset). This program was designed for use on a single shot or receiver gather. If you have concatonated a number of shot gathers, you may not wish to use this program. Seismic Unix (SU, Colorado School of Mines, CWP, program susort) should be considered for more complicated sorts on multi-gather data sets. C-Language Version.

1= Up sort, (by increasing offset)
-1= Down sort, (by decreasing offset)
NOTE:
If invoked with no options, will prompt user for input
parameters. This program uses the actual offset in 3-D
space, making it suitable for down-hole as well as surface
data.
EXAMPLE:
bsrt w001.seg 1
File w001.seg is processed by bsrt. Data are sorted by increasing offset (up sort). Thus, the near offset trace becomes trace 1 on the output data set, and the far offset trace is output last.
bsrtxxxx.seg
named according to convention (first 4char bsrt, the next 4char are the first 4char of the input file name, suffix .seg)
standard output
produces a progress bar
bsrtxxxx.lst
Echo check of input parameters in listing file, plus a table of statics applied.
