NAME

     panlt2z  -  Convert MBS sort panel from time to depth

SYNOPSIS

     panlt2z [-Nntap]  [-Ootap]  [-VTvtap]  [-Iiskip]  [-npnpanl]
     [-dtdt] [-ttmax] [-V] [-h] [-?]

DESCRIPTION

     panlt2z applies a time to depth conversion to either  common
     angle  or  common  offset  panels  (sorted to crp's) using a
     velocity field.

     Program panlt2z obtains its  parameters  from  command  line
     arguments,  and it reads the sorts of common angle or common
     offset data from a USP compatible seismic dataset.

  Command line arguments
     -Ninput
          Enter the filename of the crp sorts  after  typing  -N.
          This  is a USP-formatted dataset of crp sorts of common
          angle or common offset  data  obtained  after  prestack
          depth  migration.  The mbs common angle depth migration
          codes are pwmvzn, kmpw, fxpwmig.  The mbs common offset
          codes  are  binmig, avomig and sammig.  Programs sns or
          angs can be used to decimate and sort the  output  from
          kmpw,  fxpwmig,  pwmvzn,  binmig or avomig.  The common
          offset  migration  sequence  which  is  controlled   by
          xmig(samx),
           "prepmig -> vsamp -> vsm -> vsamp -> kray -> sammig ->
          sammerg  -> zstrch", will also create crp sorted common
          offset images.

     -Ooutput
          Enter the filename of the output panel (in depth) after
          typing -O

     -VTvtap
          The velocity field used in the mbs program.  The  first
          trace  of  the velocity field should match the location
          of the first panel.

     -Iiskip
          The panel increment (e.g. if every 10th panel was saved
          in the sort, this entry should be 10).

     -npnpanl
          This is the number of migrated angles or  offsets  gen-
          erated  by  the  mbs  code.  Typically this will be the
          number of traces per record (after sorting).   However,
          the  crp's  could  be grouped differently - for example
          program sns can produce one "super record" with all the
          crp's in a single record.

     -dtdtms
          The input sample interval in ms.  No default.

     -ttmax
          The maximum output time im ms. No default.

     -h   Enter -h for online help. Program will terminate  after
          printing this.

     -?   Enter this (or '-?' if you are running in  c-shell)  to
          get  online  help.   The  program  will terminate after
          printing this.
