cshift - subroutine to shift traces by phase rotation in the frequency domain.
call cshift(npts, x, dt, samin )
Basic Seismic
Utilities (BSU) rotates phase to shift data. Requires the
sample interval and the time shift as input. A positive
shift is a delay, a negative shift is an advance.
Fortran Version.
Arguments
npts (int)
Number of samples in a trace
x (complex)
Complex trace ( frequency domain).
dt (float)
Time shift to apply.
samin (float)
Sample interval in seconds.
flist(3)
