INSTRUMENT	SINFONI
SYNTAX	SHELL
RAWTYPE	DIST
CALL	measureQuality from $DFS_PRODUCT/DIST/$DATE: qc_DIST -d $DATE -f $primfile
PURPOSE	a) generates QC report, b) writes QC1 parameters into local database
PROCINPUT	a) $DATE in yyyy-mm-dd, b) $primfile is the PRO.CATG=DISTORTION product with the _0000.fits extension. c) raw frames are implicitely read from the AB. d) Reference DISTORTION and SLITLETS_DISTANCE are implicitely read from $DFO_QC_DIR/references/DIST.

ALGORITHM	qc_coeff_00 .. qc_coeff_21: a set of about 80 fiber frames is used to derive the optical distortion of the spectra. TBD more degrees used since 2006-06 qc_xhsift_ll .. qc_xshift_cc The distortion coefficients applied to dedicated positions on the chip. These are the center of each of the four quadrants ([@512:@512], [@1536:@1536], [@512,@1536], [@1536:@512]) and the central pixel ([@1024:@1024]). qc_sl_distavg is the average of all 31 slitlets distances. The recipe generates for each slitlets distance a QC1 parameter, but only the average and the stdev are trended. qc_sl_distrms use the scatter within the sample of 31 slitlets distances
CERTIF	Reasons for rejection: - not enough frames
COMMENTS	The recipe generates about 40 more QC parameters of less importance that are not trendend. local difference frames (current product minus last one) and reference difference frames (current product minus reference) are provided in the detailed section of certifyProducts
