| VERSION | 2.0 -- adapted for WAVE and FLAT for new pipeline 2.1 -- adapted for FORS1 (smoehler, 2007-04-11) | ||||||||||||||||||||||
| SYNTAX | MIDAS | ||||||||||||||||||||||
| CALL |
measureQuality from $DFS_PRODUCT/LAMP_STD/$DATE: inmidas -P -j "@@ $DFO_PROC_DIR/lamp_std_qc_2CCD.prg $date $PF" | ||||||||||||||||||||||
| INSTRUMENT | FORS1 | ||||||||||||||||||||||
| RAWTYPE | LAMP_STD | ||||||||||||||||||||||
| PURPOSE | compares raw and product WAVE and FLAT files for FORS1 QC assessment; the plots are later reviewed within certifyProducts. The plots are stored as Postscript file in $DFO_PLT_DIR. | ||||||||||||||||||||||
| PROCINPUT |
first raw flat and arc from AB; products: resolution table, reduced arc image, delta image, disp residuals table, wavemap image; master screen flat and normalized master flat | ||||||||||||||||||||||

lamp_std_grap1.png top left: line identifications in reduced ARC frame lower left: resolving power; lower right: residuals for row at bottom, center and top (in Angstroem) Sometimes the arc lines were not detected in all rows, so some of the coloured symbols may be missing. right: non-linear terms of fit and deviations from linear fit Sometimes the arc lines were not detected in all rows, so there may be no red crosses. Then the reduced arc lamp should be checked very carefully. top panel: date; name of disp residuals table (red), setup parameters (filter, grism, mask, chip) bottom panel: some QC1 parameters - wavelength range of central row, average residuals; mean resolution and FWHM, average number of lines identified, FWHM_ratio (see below) lamp_std_grap2.png left top row: rows and columns of normalized master flat (full range) bottom row: rows and columns of normalized master flat (central part) right: central row (top) and column (bottom) of master screen flat; top panel:name of normalized master flat field (red), setup parameters (filter, grism, mask) bottom panel: range in x over which master screen flat field has more than 10000 ADU in central row and the S/N for that range lamp_std_disp1.png full display of reduced arc frame lamp_std_disp2.png full display of normalized master flat | ||||||||||||||||||||||

| ALGORITHM |
Description of algorithms: disp: mean dispersion, averaged over all slitlets n_lin_av: number of identified lines, averaged over all slitlets | ||||||||||||||||||||||
| CERTIF |
Reasons for rejection: - only 1 flat field (weekly HC monitoring, 300V) - unusual shape of non-linear terms (e.g. double peak/valley); - curved or slanted lines in the reduced arc image; - wrong flux distribution in master screen flat (e.g. missing double peak for 300V) | ||||||||||||||||||||||
