processQC -a | |||||||||||||||||||||||||||
| INSTRUMENT | GIRAFFE | |||||||||||||||||||||||||||
| RAWTYPE | IFLAT (set of image flats plus BIAS frames); this is DETECTOR MONITORING for GIRAFFE | |||||||||||||||||||||||||||
| PURPOSE | takes a sequence of CCD linearity and gain pairs (created by DETCHECK template) and analyzes gain, contamination, linearity, fp noise | |||||||||||||||||||||||||||
| PROCINPUT |
set of LAMP,FLAT,DETCHECK files, pairs of similar exposure times, sequence between exposure level 0 and saturation level (the BIAS,DETCHECK data are not analyzed!) products analyzed: linearity table (DET_LIN_INFO), gain table (GAIN_INFO) the detmon generic recipe has been implemented as giccdlin | |||||||||||||||||||||||||||

iflat1.gif box1: middle row in first raw file (usually with 1 sec exptime); same file, middle column; closeups in X and Y; these plots help detecting unusual pattern and slopes box2: photon and fixed-pattern noise; both noise sources calculated by the recipe as pixel-to-pixel noise, and plotted with a linear fit (fp) and a square-root fit (ph); all input raw files analyzed here box3: gain results, plotted versus exptime; the true gain is the value extrapolated for exptime -> 0 box4: contamination; this is just a visualization of the four quadrants analyzed, plus the central box which serves as reference for the normalized contamination values; these values are plotted in trend_report_DETCONTA_HC.html and listed at the bootm of the QC report (conta1...conta4) box5: linearity: the results from the linearity table plotted versus exptime top panel: name of main product gain table bottom panel: no. of input raw files, mean signal, fractional fp noise, contamination values scoring: conta4, conad, qc_lin_eff, fraction_sig_fp are scored iflat2.gif screenshot of first input raw file, mainly to check for contamination | |||||||||||||||||||||||||||
| QC1PARAM |
QC1 parameters written into QC1 table: QC1db names: exptime | sigma_ph | sigma_fp | mean_signal | median_master | median_dit | conta1...4 | conad | fraction_sig_fp (normalized sigma_fp, useful for plotting) | qc_lin_eff (linearity coefficient) | |||||||||||||||||||||||||||
| ALGORITHM | computation of all QC1 params within the recipe (which is based on the detmon recipe) | |||||||||||||||||||||||||||
| CERTIF | Reasons for rejection: none (this is monitoring) | |||||||||||||||||||||||||||
