flag_noisy_pixels()

static int flag_noisy_pixels ( cpl_imagelist *  raws, cpl_image *  bpmap, cpl_image *  noisymap, int  nx, int  ny, xsh_clipping_param *  noise_clipping, xsh_instrument *  inst  )

static

Flag the noisy pixels and add to the bad pixel map

Parameters

raws	List of dark images
bpmap	Bad pixel map
nx	X size
ny	Y size
noise_clipping	Clipping parameters structure

Returns

Nb of noisy pixels found

< Array of pointers to the images

< Median of the sigmas

< Average of the sigmas

< Array of the Sigmas per pixel (all pixels)

< Same as Stackv, but without bad pixels

xsh_compute_noise_map()

cpl_frame * xsh_compute_noise_map	(	cpl_imagelist *	dataList,
		cpl_frame *	medFrame,
		xsh_clipping_param *	noise_clipping,
		xsh_instrument *	instr,

	)

Calculates the noisy bad pixel map from dark frames (equal exposures)

Parameters

dataList	List of images (from remove_crh_multiple)
medFrame	Median Frame (PRE format) created by xsh_remove_crh_multi
noise_clipping	Noise clipping parameters pointer
instr	Pointer to instrument description structure

Returns

Final master dark frame (PRE format)
