NAME

     arcscross  -  module  to  generate  crosscorrelation  output
     suitable for input to  arcscum

SYNOPSIS

     arcscross [ -Nntap ] [ -Oprefix ] [ -Pptap ] [ -nsnstr  ]  [
     -nenend  ] [ -rsnrst ] [ -renred ] [ -shot ] [ -group ] [ -V
     ] [ -? ]

DESCRIPTION

     arcscross reads in a  Pilot  and  Object  stack as output by
     arcsstack  and generates a crosscorrelation dataset suitable
     for input to  arcscum .

     arcscross gets both its data and its parameters from command
     line  arguments.   These  arguments specify the input  Pilot
     and  Object stacks, output, the start and end  records,  the
     time  window, the crosscorrelation lag and verbose printout,
     if desired.

  Command line arguments
     -N1 Pilottap
          Enter the input  Pilot Stack filename immediately after
          typing  -N1. This should include the complete 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 '/b/vsp'. There is no default  for
          this entry and piping into this routine is not allowed.

     -N2 Objecttap
          Enter the  Object  Stack   filename  immediately  after
          typing  -N2.   This  input 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 '/b/vsp'.  There  is
          no  default for this entry and piping into this routine
          is not allowed.

     -s st
          Enter start time [ms].  Default value is the first sam-
          ple.

     -e ed
          Enter end time [ms].  Default value is last sample.

     -rs nrst
          Enter start record number.  Default value is the  first
          record.

     -re nred
          Enter end record number.  Default value is last record.

     -lag ms
          Enter the lag [ms] for the crosscorrelation.  The  out-
          put  will  contain  information  from  -lag  to  +lag .
          Default value is 100 ms.

     -V   Enter the command line argument '-V' to get  additional
          printout.

     -?   Enter the command line argument '-?'  or   -h   to  get
          online  help.   The  program  terminates after the help
          screen is printed.
