NAME

     bdstat  - module to do statistical analysis over  window  of
     seismic data

SYNOPSIS

     bdstat [ -Nntap ] [ -Ootap ] [  -nsnstr  ]  [  -nenetr  ]  [
     -rsnrst  ] [ -renred ] [ -sstart ] [ -eend ] [ -hwd0hwd0 ] [
     -hwd1hwd1 ] [ -constconst ] [ -ppadval ] [ -V ] [ -? ]

DESCRIPTION

     bdstat is a statistical analysis routine constructed  to  be
     run  in  connection  with Landmark data that has been previ-
     ously passed through the lmpicks routine.

INPUT

     bdstat gets both its data and parameters from  command  line
     arguments.  These arguments specify the input, output, trace
     start and end, record start and end, header word to  contain
     window  start  and  end  times,  a  constant window size (if
     applicable) and a verbos output flag.

  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 stats filename immediately after  typ-
          ing  -O.   The  output files  l be generated containing
          the indicated statistics from  data  amplitudes  within
          the user defined window.

     -ns nstr    [default: first trace]
          Enter start trace.

     -ne netr    [default: last trace]
          Enter end trace.

     -rs nrst    [default: first record]
          Enter start record.

     -re nred    [default: last record]
          Enter end record.

     -s start    [default: sample 1]
          Enter start time.


     -e end    [default: last sample]
          Enter end time.

     -hwd0 hwd0    [default: none]
          Enter header mnemonic containing window start  time  in
          milliseconds.

     -hwd1 hwd1    [default: expects a constant if not present]
          Enter header mnemonic containing  window  end  time  in
          milliseconds.

     -const const    [default: 0]
          Enter window size in milliseconds. (will not be used if
          both -hwd0 and -hwd1 are present)

     -p padval    [default: -15999]
          Enter value used to designate no pick when

     -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.
