NAME

     becky  - find the time across each seismic lobe. Save  as  a
     square wave

SYNOPSIS

     becky [ -Nntap ] [ -Ootap ] [ -tsts ] [ -tete ] [ -mmode ] [
     -ppol ] [ -nsnstr ] [ -nenetr ] [ -rsnrst ] [ -renred ] [ -V
     ] [ -? ]

DESCRIPTION

     becky calculates the time spent in  each  seismic  lobe  and
     saves  these  data  as  a trace of square waves whose sample
     values are the measured times in seconds. The algorithm  can
     be  used in "precise" mode or "fast" mode.  The precise mode
     finds the precise time of the zero crossing between  seismic
     samples  using  linear  interpolation.  The fast mode counts
     samples and multiplies by delta t.  The polarity mode simply
     multiplies  the  calculated  times  by the sign of the input
     lobe.

  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).

     -ts ts
          Enter the start time of the  application  window.   The
          default is the beginning of the trace.

     -te te
          Enter the end time  of  the  application  window.   The
          default is the end of the trace.

     -m mode
          Enter the calculation mode: 0 = fast mode; 1 =  precise
          mode.  Default = 1

     -p pol
          Enter the polarity option:  0  =  normal  output;  1  =
          polarize output.  Default = 0


     -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.
