NAME

     velmax  - output velocity  field  corresponding  to  maximum
     semblance

SYNOPSIS

     velmax [ -Nntap ] [ -Ootap ] [ -sist ] [ -eiend ] [  -nsnstr
     ] [ -nenetr ] [ -rsnrst ] [ -renred ] [ -V ] [ -? ]

DESCRIPTION

     velmax read each semblance record (from velspec or taupspec)
     in  the  data set and find the velocities that correspond to
     the semblance maxima. Output this velocity trace.

     velmax gets both its data and its  parameters  from  command
     line  arguments.  These arguments specify the input, output,
     the start and end traces, and verbose printout, if desired.

  Command line arguments
     -N ntap
          Enter the input data set name or file immediately after
          typing -N unless the input is from a pipe in which case
          the -N entry must be omitted.  This input  file  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'.

     -O otap
          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).

     -s ist
          Enter the start time of the design window.  The default
          is  the  beginning  of  the  trace.  The filter will be
          applied to the whole trace, regardless of the -s and -e
          entries.

     -e iend
          Enter the end time of the design window.   The  default
          is the end of the trace.

     -ns nstr
          Enter the start trace number.  The default is the first
          trace of the record.

     -ne netr
          Enter the end trace number. The  default  is  the  last
          trace of the record.

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

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

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

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