NAME

     gscl - Generalized Scaling Program

SYNOPSIS

     gscl  [-Ninput]  [-Ooutput]  [-Aalpha]  [-Xxmult]  [-Eexpnt]
     [-Irecstart] [-Jrecordend] [-V] [-h]

DESCRIPTION

     gscl applies a constant gain curve to the  data  to  correct
     for  cylindrical  spreading and decay of the wavefront.  The
     input is a USP compatible dataset and the following  command
     line  arguments.  The basic equation for scaling the data is
     essentially:

        g(t)= xmult*(10**expnt)*(t**alpha)*f(t)


  Command line arguments
     -N input
          Enter the input dataset name after typing -N.

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

     -A alpha
          Enter time exponent after typing -A.  Default is .5.

     -X xmult
          Enter constant multiplier after typing -X.  This is the
          value  the gain curve will have at one second.  Default
          is 1.

     -E expnt
          For an exponential gain curve, enter the exponent after
          typing -E.  Default is 0.

     -I recstart
          After typing -I, enter the first record to process from
          the input data.  Default is 1.

     -J recordend
          After typing -J, enter the record number  of  the  last
          record  to  process from the input data. Default is all
          input records.

     -V   Enter -V for a verbose printout.

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