NAME

     norm - Normalize a Seismic Dataset

SYNOPSIS

     norm [-N ntap] [-O otap] [-I nsamp] [-V ] [-h ]

DESCRIPTION

     norm will  normalize  a  USP-formatted  seismic  dataset  by
     creating  an  "average"  trace for each record, then scaling
     each trace  within  the  record  by  this  "average"  trace.
     Before  the scaling is performed, the "average" trace may be
     smoothed by averaging over samples within a  user  specified
     window size. The description of the smoothing is found below
     with the description of the parameter nsamp. The output will
     be a USP-formatted seismic dataset.

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

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

     -I nsamp
          Enter the number of samples  in  the  smoothing  window
          after typing -I.  In smoothing the "average" trace, the
          nth sample out will be an average of the samples within
          the  window  over a range of (n-nsamp/2,n+nsamp/2). The
          samples at the first of the trace (less  than  nsamp/2)
          and  at the end of the trace (greater than last sample-
          nsamp/2) will  be  unchanged.   The  default  for  this
          parameter is 10 samples.

     -V   Enter -V for a verbose printout.

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

BUGS
