http://www.ahay.org/blog/2013/07/01/program-of-the-month-sftime2depth/

Parameters
		float dz= Depth sampling (default: d1)   float eps=0.01 stretch regularization   int extend=4 Interpolation accuracy   bool intime=n [y/n] y if velocity is in time rather than depth   int nz= Number of depth samples (default: n1)   bool slow=n [y/n] If y, input slowness; if n, velocity   bool twoway=y [y/n] if y, two-way traveltime   file velocity= auxiliary input file name   float z0=0. Depth origin
