NAME

     scomb - Combine Two Seismic Datasets

SYNOPSIS

     scomb [-A inputA] [-B inputB] [-O output]  [-C  cardin]  [-a
     Amult]  [-b  Bmult]  [-e epsilon] [-SUM] [-DIV] [-MULT] [-V]
     [-h]

DESCRIPTION

     scomb will combine by summing, dividing, or multiplying  two
     seismic  datasets,  each  of which may be scaled by a multi-
     plier.  The inputs are USP compatible seismic  datasets  and
     command line arguments.

  Command line arguments
     -A inputA
          Enter the name of the first input dataset after  typing
          -A.

     -B inputB
          Enter the name of the second input dataset after typing
          -B.

     -O output
          Enter the name of the output dataset after typing -O.

     -C cardin
          Enter the name of the  input  card  deck  for  multiple
          scale  factors.   Use the "catpat scomb" command to see
          the format of the card deck.

     -a Amult
          Enter a scalar multiplier  to  be  applied  to  inputA.
          Default is 1.0.

     -b Bmult
          Enter a scalar multiplier  to  be  applied  to  inputB.
          Default is 1.0.

     -e epsilon
          This value is used when requesting division. This is an
          amount  to  be added to inputB before inputA is divided
          by inputB. Default is 0.0.

     -SUM If this flag is present the output will be:
                        Amult*inputA + Bmult*inputB.

     -DIV If this flag is present the output will be:
                        Amult*inputA / ((Bmult*inputB) + epsilon)

     -MULT
          If this flag is present the output will be:
                        Amult*inputA * Bmult*inputB.

     -V   Enter -V for a verbose printout.

     -h   Enter -h for online help.  Program will terminate after
          printing this.
