suramp

seismic software,very useful

SURAMP - Linearly taper the start and/or end of traces to zero.
suramp <stdin >stdout [optional parameters]
Required parameters:
	if dt is not set in header, then dt is mandatory
Optional parameters
	tmin=tr.delrt/1000	end of starting ramp (sec)
	tmax=(nt-1)*dt		beginning of ending ramp (sec)
	dt = (from header)	sampling interval (sec)
The taper is a linear ramp from 0 to tmin and/or tmax to the
end of the trace.  Default is a no-op!
