NAME

     stomp.x  - script to mimic stomp: STOchastic  Multiple  Pre-
     clusion

SYNOPSIS

     stomp.x [ -NNM ] [ -OOF ] [ -vVF ] [ -rsrs ] [ -rere ] [ -h,
     -H ]

DESCRIPTION

     stomp.x

     is a script file (written in c-shell) that invokes  a  pipe-
     line  of  USP programs to implement stochastic multiple pre-
     clusion (see spring 1989 RGTS item by Paul Favret  and  Bill
     May).  The script file is run just like any USP program with
     stdin and stdout (pipe in/out capabilities) and command line
     arguments.   A  portion  of the input data is chosen, normal
     moveout is used to flatten what is to be kept,  the  gathers
     are  then randomly ordered, median filtered, re-ordered, and
     finally the NMO is restored.

     Note that since stomp.x is a script file you can copy it and
     use it as a template to build your own favorite scripts.

     stomp.x gets both its data and its parameters  from  command
     line  arguments.  These arguments specify the input, output,
     the start and end records, and the velocity tape file  name.
     If  a  velocity  is  specified you must also provide a group
     interval.

  Command line arguments
     -N NM
          Enter the input data set name or file immediately after
          typing -N.  This input put file should include the com-
          plete path name if the  file  resides  in  a  different
          directory.  Example -N/b/vsp/dummy tells the program to
          look for file 'dummy' in directory 'vsp' stored on  the
          'b' disk.

     -O OF
          Enter the output data  set  name  or  file  immediately
          after typing -O.  This output file is not required when
          piping the output to another process.  The output  data
          set also requires the full path name (see above).

     -v VF
          Enter the name of  the  velocity  tape  disk  file  (no
          default).

     -rs nrst
          -re nred  Only  records  between  and  including  these
          values  will be used.  Default values are the first and
          last records.

     [-h, -H]
          Enter the command line argument -h or -H to get  online
          help.   The program terminates after the help screen is
          printed.

BUGS

     Nearly all standard USP programs  have  little  online  help
     screen  dumps invoked by entering '-?' after the name of the
     program.  stomp.x is an exception in that -H  or  -h  invoke
     this feature.
