Parameters
		int CDPtype=   string a=   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   string s= 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 maximum stretch allowed   file velocity= auxiliary input file name
