NAME

     dspace - Determine  Disk  Space  for  3D  V(z)  Phase  Shift
     Poststack Depth Migration

DESCRIPTION

     dspace

     The easiest way to use this program is to build an executable
          script by typing:
                      catpat 3dvzmig > 3dvzmig.job
          Then edit the 3dvzmig.job and set:
          RUN_DSPACE=YES
          RUN_FFT3D=NO
          RUN_CMMVZ3D=NO
          Then execute the script. The approximate amount of disk
          space  needed  for each of the programs will be written
          to the screen and to a print file.  You can then set:
          RUN_DSPACE=NO
          RUN_FFT3D=YES
          RUN_CMMVZ3D=YES
          Then execute the script again, and the  migration  will
          be performed.
