NAME

     scalu  -  "batch sister" program of ILIS program SSCALE that
     performs  scaling  of  seismic data to correct for spherical
     divergence, array and q effects and/or adjust amplitudes for
     agreement  with  synthetics using a scaler file generated by
     SSCALE.


     THIS IS A PRELIMINARY VERSION. REPORT PROBLEMS TO ZJHW0B  OR
     ZROL01 AT TRCVM.

SYNOPSIS

     scalu [ -mdmode ] [ -Nntap ] [ -Ootap ] [ -Mmtap ] [ -VIvsis
     ]  [  -TDtdfnf  ] [ -tyveltyp ] [ -spisphd ] [ -ariarray ] [
     -qciq ] [ -vqqvalue ] [ -cmicomp ] [ -V ] [ -? ]


  Command line arguments
     -md mode
          Enter the desired mode immediately  after  typing  -md.
          The modes are:

                1 - scaling for spherical divergence and/or
                    array effects and/or q effects, corrections.
                    a velocity function is required - rms or
                    interval.

                2 - scaling to adjust amplitudes to agree
                    with synthetics by applying a scaler ri.

                3 - do both 1 and 2.


     -N ntap
          Enter the input file name immediately after typing  -N.
          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'.  Note: Input may be for-
          mat 1 or 3.


     -O otap
          Enter the output file name immediately after typing -O.
          The  output  data  set  also requires the complete path
          name (see ntap).


     -M mtap
          If mode = 2 or  3  (see  above)  enter  the  file  name
          immediately  after  typing -M.  This is the scaler file
          created by ILIS program SSCALE.  This is a seismic like
          file.  The single RI in this file ( -ri ) is applied to
          the seismic input.


     -VI vsis
          If mode = 1 or 3 (see above) enter the  file  name  for
          the  seismic  like file that contains interval velocity
          functions.


     -TD tdfnf
          If mode = 1 or 3 (see above) enter the  file  name  for
          the TDFN velocity file - interval or RMS velocities.


     -ty veltyp
          If mode = 1 or 3 and a TDFN file provides  the  veloci-
          ties,  this  parameter  must  be  specified as 'rms' or
          `int'.


     -sp isphd
          If mode = 1 or 3, this parameter  informs  the  program
          whether  or  not correction for spherical divergence is
          to be done.  (0 = off, 1 = on)  The default is ON.


     -ar iarray
          If mode = 1 or 3, this parameter  informs  the  program
          whether  or  not  correction for array effects is to be
          done.  (0 = off, 1 = on) The default is OFF.


     -qc iq
          If mode = 1 or 3, this parameter  informs  the  program
          whether  or not correction for q effects is to be done.
          (0 = off, 1 = on) The default is OFF.


     -qv qvalue
          If mode = 1 or 3 and q correction is turned  "on"  then
          this  parameter  is  required.   If  not  specified the
          default will be used - 50.0.


     -cm icomp
          If mode = 1 or 3, this  parameter  indicates  the  com-
          ponent  type,  as  follows:  (The  default  is  0, omi-
          marine.)
                 0 - omni-marine
                 1 - vertical-land
                 2 - horizontal-land


     -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.
