BDUMP

Most user interest is in a single shot gather, so the program focuses largely on receiver headers plus a single header for the shot. In that case, one may supress shot header display after the first. Sometimes, as in reciprocal refraction shooting, the interest is in a geophone gather. In that case, one should display all shot headers. The command is issued from a terminal:

 bdump infile iskip 
  
 infile:    =name of input file 
 iskip:     =0 supress shot header display after 1st 
            =1 display all shot headers

The output file is bdump.lst which may be viewed in any editor or cat to the screen. A sample of the output:

Each trace row is a geophone associated with the shot.
