| PURPOSE |
Comparison of raw, master and reference BIAS files
for UVES QC assessment;
QC1 values are calculated and fed into the QC1 table.
QC1 plot(s) and/or display(s) are generated,
and later reviewed within certifyProducts. The generated plots stored in $DFO_PLT_DIR/$DATE with the name r.<DPid>_tpl_0000.fits.png where <DPid> is the Data Product Identification of the first frame of the template. | |||||||||||||||||||||||||||

bias_red.montage.png A montage image made up of the following individual reports simply for the purposes of easier/better display in XV during the certification process. Created together with the reference montage (see below) within the uves.MeasureQuality script. Can be recreated manually by calling the script uves.makeQCreportMontage -a <AB>, see uves.makeQCreportMontage -h for more details. bias_red.montage.ref.png A montage image made up from the individual QC reports of the reference AB located by the script uves.getRefAB. During certification, the two montage images are blinked to facilitate identification of unusual features. This reference montage created at the same time as the AB montage (see above).The montage of the reference AB is easily identified during the blinking as the one with the grey background. bias_red_0000.fits.png box 1: comparison LOWER master (red), UPPER master (green) <-> raw (black); middle row and middle column, full pixel range, in ADU box 2: comparison LOWER master (red), UPPER master (green) <-> raw (black), expansion in x; middle row and middle column, central 100 pixels, in ADU box 3: ratio master/reference for LOWER; central row for all columns (black) in ADU; central column for all rows (green) in ADU, offset for clarity by +0.10 box 4: ratio master/reference for UPPER; central row for central 100 columns (black) in ADU; central column for central 100 rows (green) in ADU, offset for clarity by +0.10 box 5: histogram: all pixel values in log frequency histogram; raw: black, LOWER master: red, UPPER master: red; there should be a dominant peak with Gaussian shape (which translates to parabola shape in this log freq diagram) box 6: structure description; all columns and all rows are collapsed and then all rows (top) and all columns (bottom, offset by -0.10 for clarity) are displayed; top panel UPPER, lower panel LOWER top panel: name of analyzed master bias frame, along with the name of the first RAW, the reference used etc bottom panel: some QC1 parameters (median_master; raw RON, master RON, expected RON=raw/sqrt(5), structure parameters) bias_red_0000.fits_1.ima.png full display of raw frame bias_red_0000.fits_2.ima.png full display of LOWER chip master frame (box: area to be displayed in bias_red_0000.fits_4.png) bias_red_0000.fits_3.ima.png full display of UPPER chip master frame (box: area to be displayed in bias_red_0000.fits_5.png) bias_red_0000.fits_4.ima.png closeup display of LOWER chip master frame bias_red_0000.fits_5.ima.png closeup display of UPPER chip master frame bias_red_0000.fits_6.ima.png full display of LOWER chip master frame minus reference frame bias_red_0000.fits_7.ima.png full display of UPPER chip master frame minus reference frame | |||||||||||||||||||||||||||

Description of algorithms: Algorithms for pipeline created keywords are (in principal) described in the pipeline user's manual
| |||||||||||||||||||||||||||
| CERTIF |
Reasons for rejection: - unusually high bias level or RON level (unless representative); - unusual structure (compare panel 2 plots with older/reference version); - non-Gaussian shape of histogram; - DATANCOM lower than usual (5), especially if N=5 version nearby in time The closeup displays are useful to check for patterns (e.g. pickup noise) which should not be there. | |||||||||||||||||||||||||||
