                               PROCESS SADD

Document date: 7 August 1992

PROCESS SADD performs a scalar addition to the seismic traces, i.e. a 
constant number specified by the parameter SCALAR is added to every
amplitude.  Only those shot/rps and traces specifically given have the 
scalar addition applied.  There is no spatial interpolation.


PARAMETER DICTIONARY
--------- ----------

SCALAR - The scalar to add to the trace.
         Preset = 0.            e.g.   scalar 10.e3

FNO    - The first shot/rp number the parameter list applies to.
         Preset = the first shot/rp received.    e.g.   FNO 101

LNO    - The last shot/rp number the parameter list applies to.
         Preset = the last shot/rp received.    e.g.   LNO 101

FTR    - The first trace number the parameter list applies to.
         Preset = the first trace of each shot/rp.    e.g.   ftr 10

LTR    - The last trace number the parameter list applies to.
         Preset = the last trace of each shot/rp.    e.g.   ltr 10

END    - Terminates the parameter list.
