system/seismic/Mtshift.c
Compute angle gathers for time-shift imaging condition

 
Synopsis
        sftshift < Fstk.rsf velocity=Fvel.rsf dip=Fdip.rsf > Fang.rsf na=nv da=1./(nv-1) a0=0. extend=4 cos=n

 
Parameters

bool cos=n [y/n]
if n, convert pseudo-v to pseudo-tan(theta);
if y, compute cos(theta) from 1/|pm|
 
float da=1./(nv-1)
