SURESAMP - Resample in time

suresamp <stdin >stdout [optional parameters]

Required parameters:
none

Optional Parameters:
nt=tr.ns number of time samples on output
dt=tr.dt/10^6 time sampling interval on output
tmin=tr.delrt/10^3 first time sample on output

Example 1: (assume original data had dt=.004 nt=256)
sufilter <data f=40,50 amps=1.,0. |
suresamp nt=128 dt=.008 | ...
Note the typical anti-alias filtering before sub-sampling.
Example 2: (assume original data had dt=.004 nt=256)
suresamp <data nt=512 dt=.002 | ...
