xsh_subtract_sky_nod()

cpl_frameset * xsh_subtract_sky_nod	(	cpl_frameset *	raws_ord_set,
		xsh_instrument *	instrument,
		int	mode_fast
	)

Subtract A to B frames. Note that the order of input frames MUST be AB[B1A1...]. In the output frameset, we always have A-B, B-A, A1-B1, B1-A1 in this order.

Parameters

raws_ord_set	Raw frames frameset
instrument	Pointer to instrument structure
mode_fast	specify of fast mode is set

Returns

Frameset of A-B and B-A frames
