NAME

     fsi - Create A Focal Surface Image

SYNOPSIS

     fsi [-NCntap] [-NPntap2] [-Ootap] [-a] [-b] [-n N] [-V]

DESCRIPTION

     fsi creates a mosaic of the best pieces of the  v(z)  migra-
     tions  created  by  cubevz.  The user indicates which pieces
     are considered "the best" via picks from program apkr.   The
     output  is a migrated dataset in time.  Normally, fsi is run
     through an apkr.flow script.

  Command line arguments
     -NC ntap
          Enter the name of the input cube dataset  after  typing
          -NC.  This  dataset  is  produced  by  running  program
          cubevz.

     -NP ntap2
          Enter the name of the input picks dataset after  typing
          -NP.  This dataset is produced by running program apkr.

     -O otap
          Enter the  name  of  the  output  focal  surface  image
          dataset after typing -O.

     -a   If this flag is present on the command line,  an  image
          will  be extracted for every location in the input cube
          dataset.  The picks will be interpolated  and  extrapo-
          lated as necessary.

     -b   If this flag is present on the command line,  an  image
          will  be  extracted  between  the first and last picked
          locations.  The picks in between will  be  interpolated
          as necessary.

     -n N This is the pick index multiplier.  It is the number of
          locations  picked in program apkr divided by the number
          of traces per record in the cube input.  This is neces-
          sary  if  the  cube  was  interpolated to a finer trace
          interval before picking.

     -V   Enter -V for a verbose printout.
