Parameters
		float V0= V0 1.5..3   bool avosemblance=n [y/n] if y, compute AVO-friendly semblance   bool dbgt0=n [y/n] if y compute with Rnip=Velocity   bool diffsemblance=n [y/n] if y, compute differential semblance   int extend=4 trace extension   bool half=n [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   int nb=2 semblance averaging   int ns=1   string offset= auxiliary input file name   bool semblance=n [y/n] if y, compute semblance; if n, stack   bool slowness=n [y/n]   float smax=2.0 maximum heterogeneity   float str=0.5 maximum stretch allowed   bool weight=y [y/n] if y, apply pseudo-unitary weighting
