NAME

     usp_sps - module  to  create  minimal  sps  format  geometry
     files,  using  x,y  information  from the USP headers.  This
     file can then be converted to an aps  file  (using  sps_aps)
     containing  polarization  info,  which  can  then be used to
     insert this polarization info  back  into  the  USP  headers
     (using aps_usp).  If you don't even have sps geometry files,
     usp_sps can get you started.

SYNOPSIS

     usp_sps [ -Nntap ] [ -Ssps_source-file ]  [  -Rsps_receiver-
     file ] [ -Xsps_relation-file ] [ -MCLmulti_component_list ]
     [ -V ] [ -? ]

DESCRIPTION

     usp_sps gets both its data and its parameters  from  command
     line  arguments.  You may use sticky or non-sticky arguments
     as you wish.


  Command line arguments
     -Nseismic_multicomponent-infile(s)
          Enter the filename for the  seismic  input  dataset(s).
          usp_aqp  uses  the multicomponent i/o library uspio; cf
          the man pages for prgmMC for details of data-set organ-
          ization.

     -Saps_source-file
          Enter  the  filename  for  the  seismic-source   output
          dataset,  in  sps format.  This filename should include
          the complete path, if the file resides in  a  different
          directory.

     -Raps_receiver-file
          Enter the filename for the receiver output dataset,  in
          sps  format.  This filename should include the complete
          path, if the file resides in a different directory.

     -Xaps_relation-file
          Enter the filename for the "relation"  output  dataset,
          in  sps  format.  This filename should include the com-
          plete path, if the file resides in a  different  direc-
          tory.

     -V   Enter this command  line  argument  to  get  additional
          printout.

     -? or -h
          Enter the command line argument  '-?'   or  -h  to  get
          online  help.   The  program  terminates after the help
          screen is printed.

DISCUSSION

     usp_sps only writes a minimal sps-format file.  In  particu-
     lar,  since  it does not have available most of the informa-
     tion required for the sps headers, it does not  write  these
     at  all.   Normally, you can make do with a bogus set of sps
     headers, since they are only needed to satisfy  the  format-
     ting  requirements  for  subsequent  application of sps_aps.
     (You  can  find   such   a   set   of   bogus   headers   in
     ~usp/src/cmd/usp_sps/sps.hdrs.)   Just  patch these onto the
     front of the files created by usp_sps.  (You need an identi-
     cal set for all three: source, receiver, relation.)

BUGS

     None known.
