Configuration parameters

parameter	default value	description
`source`	DetInfo(:Camera)	source of data
`key_in`		key for input `ndarray<const T,NDIM>`
`key_out`	calibrated	output key for calibrated image saved in event
`do_peds`	false	true: pedestals subtracted if available in calib store
`do_cmod`	false	true: common mode correction is evaluated and applied [Ref.]
`do_stat`	false	true: bad/hot pixels in pixel_status are masked
`do_mask`	false	true: mask is applied if the file `fname_mask` is available (1/0 = good/bad pixels)
`do_bkgd`	false	true: normalized background is subtracted if the file `fname_bkgd` is available
`do_gain`	false	true: `pixel_gain` correction is applied if available in calib store
`do_nrms`	false	true: per-pixel threshold is applied if `pixel_rms` is available in calib store
`do_thre`	false	true: low level `threshold` in ADU is applied
`fname_bkgd`		input file name for background, applied if the file name is specified
`fname_mask`		input file name for mask, applied if the file name is specified
`masked_value`	0.	intensity value (in ADU) substituted for masked pixels
`threshold_nrms`	3.	threshold as a number of sigmas to `pixel_rms` parameters
`threshold`	0.	common low level threshold in ADU
`below_thre_value`	0.	intensity substituted for pixels below threshold
`bkgd_ind_min`	0	minimal index in flatten ndarray, which is used for background normalization
`bkgd_ind_max`	100	maximal index in flatten ndarray, which is used for background normalization
`bkgd_ind_inc`	2	index increment in flatten ndarray, which is used for background normalization
`print_bits`	0	verbosity: =0 - print nothing +1 - input pars +2 - calibration parameters +4 - common mode algorithm parameters +8 - ndarray parameters; type, ndim, shape, etc. +16- time stamp for each event +32 - first 10 elements of the raw image data +64 - first 10 elements of the calibrated image data
