Synopsis
		sfnmo < cmp.rsf velocity=velocity.rsf > nmod.rsf offset=offset.rsf mask=msk.rsf half=y str=0.5 mute=12 slowness=n squared=n h0=0. extend=4

Compatible with sfvscan.

Parameters
		int extend=4 trace extension   float h0=0. reference offset   bool half=y [y/n] if y, the second axis is half-offset instead of full offset   string mask= auxiliary input file name   int mute=12 mute zone   string offset= auxiliary input file name   bool slowness=n [y/n] if y, use slowness instead of velocity   bool squared=n [y/n] if y, the slowness or velocity is squared   float str=0.5 minimum stretch allowed   file velocity= auxiliary input file name
