Synopsis
		sfcat > out.rsf order= space= axis=3 nspace=(int) (ni/(20*nin) + 1) o= d= [

sfmerge inserts additional space between merged data.

Parameters
		int axis=3 Axis being merged   float d= axis sampling   int nspace=(int) (ni/(20*nin) + 1) if space=y, number of traces to insert   float o= axis origin   ints order= concatenation order [nin]   bool space= [y/n] Insert additional space. y is default for sfmerge, n is default for sfcat
