void __attribute__

(

(constructor)

)

int clean_bad_pix	(	const char *	IDin_name,
		const char *	IDbadpix_name
	)

removes bad pixels in cube

int IMG_REDUCE_centernormim	(	const char *	IDin_name,
		const char *	IDref_name,
		const char *	IDout_name,
		long	xcent0,
		long	ycent0,

Recenter and normalize image

if mode = 1, shared memory loop

compute offset
