SUSHIFT - shifted/windowed traces in time

sushift <stdin >stdout [tmin= ] [tmax= ]

tmin= min time to pass
tmax= max time to pass

(defaults for tmin and tmax are calculated from the first trace.
verbose= 1 echos parameters to stdout

Background :
tmin and tmax must be given in seconds

In the high resolution single channel seismic profiling the sample
interval is short, the shot rate and the number of samples are high.
To reduce the file size the delrt time is changed during a profiling
trip. To process and display a seismic section a constant delrt is
needed. This program does this job.

The SEG-Y header variable delrt (delay in ms) is a short integer.
That's why in the example shown below delrt is rounded to 123 !
