NAME

     dipnmo  - module to apply/remove normal  moveout  correction
     with dip

SYNOPSIS

     dipnmo [ -Nntap ] [ -Ootap ] [ -dtheta ] [ -vvmod ] [  -nsns
     ] [ -nene ] [ -rsirs ] [ -reire ] [ -svvrs ] [ -evvre ] [ -S
     ] [ -R ] [ -V ] [ -? ]

DESCRIPTION

     dipnmo takes a set of traces, applies the dynamic correction
     and shifts the traces by the calculated moveout time subject
     to the dip term

     dipnmo gets processing controls from the command line.  Rea-
     sonable  defaults  are setup.  In addition, if no input file
     name is given, the binary trace data are expected to  be  on
     the standard input. However, a velocity model must be speci-
     fied.

  Command line arguments
     -N ntap
          Enter the full path of the  file  containing  the  data
          set.   If  not specified, input is expected to be stan-
          dard input.  If standard input  is  not  specified  and
          there  is  no  input,  e.g., program run in background,
          expect a termination. (default standard input )

     -O otap
          Enter the full path of the output file.  If not  speci-
          fied,   output  is  expected  to  be  standard  output.
          (default standard output )

     -v vmod
          Enter the full path of the file containing the velocity
          model.   This file is in SIS format and is RMS velocity
          versus two way travel time. Program will  stop  if  the
          velocity  model  file  is not given. The velocity model
          must have the same sample interval and number  of  sam-
          ples  as the trace data.  There is one velocity record,
          consisting of a single velocity-time  trace,  for  each
          seismic  record.   none ).  The header of the vmod file
          must be consistent with that of  the  data  file.   For
          this  purpose, the program velin (for interpolated mul-
          tiple velocity functions) is used to generate the velo-
          city file in SIS format.

     -d theta
          Enter the dip angle in degrees (default = 0.0).

     -ns ns
          First trace in record to process (default = 1 )

     -ne ne
          Last trace in  record to process (default = all )

     -rs irs
          First  record to process (default = 1 )

     -re ire
          Last  record to process (default = all )

     -sv vrs
          First  velocity record to process (default = 1 )

     -ev vre
          Last  velocity record to process (default = all )

     -S   If present apply internal trace header statics  (before
          nmo).

     -R   If present remove normal moveout

     -V   Verbose mode. List command line  and  lineheader  input
          parameters.

     -?   Query mode.  With this flag, nmo will give  a  descrip-
          tion  of  the  command line arguments and stop the pro-
          gram.
