Parameters
		bool adj=n [y/n] if perform derivative filtering   bool diff#=(n,n,...) [y/n] differentiation on #-th axis   bool domod=y [y/n] if y, apply half-derivative filter   float eps=0.001   float epst2=0.001   bool hd=y [y/n]   int pad=nt output time samples   float passthr=0.001   int rect#=(1,1,...) smoothing radius on #-th axis   int repeat=1 repeat filtering several times   bool sm=y [y/n] if y, do adjoint integration   int sw=0 if > 0, select a branch of the antialiasing operation   float v0= constant velocity (if no velocity=)   float v_1=   float v_2=   float v_3=   float v_4=   string velocity= velocity file (auxiliary input file name)
