badpixelmap.png Bad Pixel Map, snapshot from SkyCtaTool r.VCAM.2022-02-13T15:41:43.246_tpl_0000_1.png Left plot shows the saturation level (blue horizontal line), the raw frame medians (red circles), the reset corrected values obtained from the diagnose product (blue circles), and the same values for three selected channels. and a linear fit the the red points. Right box shows the deviation between the linear fit to the non-linear red circles. r.VCAM.2022-02-13T15:41:43.246_tpl_0001_1.png fluxes of the DETCHECK frames (=5sec flats), only channel #7, normalized to: last frame = 1. fit via: f(x) = a + b * |x-c| - exp(-e*(x-d)), where b * |x-c| represents the persistence scaled with the DIT of the LINEARITY flats, a-1 is the relative persistence, c is time of the brightest LINEARITY flat and b represents the DIT sequence within the template. 1 - exp(-e*(x-d)) represents the warmup of the calibration flat field lamp, d is the lamp switch-on time and e is the warmup speed. r.VCAM.2022-02-13T15:41:43.246_tpl_0002_1.png fluxes of the DETCHECK frames (=5sec flats), all channels are shown, each channel is normalized to: last frame = 1. while the lamp warmup is common among all detectors and channels, the persistence varies from channel to channel. | ||||||||||||||

QC.BAD_PIXEL_STAT, qc_badfrac, fraction of bad pixel QC.BAD_PIXEL_NUM, qc_nbadpix, number of bad pixel QC.LINEARITY, qc_linearity, linearity correction at 10000 ADU in per cent QC.LINERROR, qc_linerror, error of QC.LINEARITY QC.SCREEN_TOTAL, qc_screen_total QC.SCREEN_STEP, qc_screen_step QC_DIT_MIN, qc_dit_min, smallest DIT within the sequence QC_DIT_MAX, qc_dit_max, largest DIT within the sequence QC_LINE_MEDMIN, qc_line_medmin, smallest flatfield counts within the sequence QC_LINE_MEDMAX, qc_line_medmax, largest flatfield counts within the sequence | ||||||||||||||
| ALGORITHM |
Description of algorithms: see pipeline manual | ||||||||||||||
| CERTIF |
Quality diminishing features (not under control, but tolerated) : - As the recipe is rather inflexible, the flux range must exceed a certain threshold for all detectors, otherwise the recipe fails. | ||||||||||||||
