1.1 -- 2006-07-07 certified 2.0 -- 2009.05.05 completely re-written in Python with added QC functions and images
from $DFS_PRODUCT/DARK/$DATE:
QCsinfo_dark.py -a $AB_name -i $level_of_interaction: 0-2
b) generates QC report
c) writes QC1 parameters into local list
b) $primfile is the PRO.CATG=MASTER_DARK product with the _0000.fits extension.
c) raw frames are implicitely read from the AB.
d) Reference MASTER_DARK and BP_MAP_HP are implicitely read from $DFO_QC_DIR/references/DARK.

UL: The mean (collapsed) columns of the current master dark (blue), the reference master dark (red), and the difference between the two (black).
UC: The mean (collapsed) rows of the current master dark (blue), the reference master dark (red), and the difference between the two (black).
UR: Logarithmic histograms of the current master dark (blue), the reference master dark (red), and the difference between the two (black).
LL: Image of current master dark.
LC: Image of current hot pixel map.
LR: Logarithmic histograms of the difference of the raw dark frames. Second raw minus first raw (purple), third raw minus second raw (turquois).
FITSNAME, DBNAME , typical value, description:
QC.DARKMED.AVE , qc_darkmed_ave, (20.207021), Average of raw darks medians
QC.DARKMED.STDEV , qc_darkmed_stdev (1.741316), STDEV of raw darks medians
QC.RONRMS , qc_ronrms, (441.092956), RMS on Read Out Noise
QC.DARKFPN , qc_dark_fpn, (2.53823), Fixed Pattern Noise of combined frames
QC.RON1 , qc_ron1, (3.517257), Read Out Noise from first raw frame pair
QC.RON2 , qc_ron2, (3.524859), Read Out Noise from second raw frame pair
QC.BP-MAP.METHOD , qc_bpm_method, (Normal), bad pixel map method (here hot pixel map)
QC.BP-MAP.NBADPIX, qc_bpm_nbadpix, (200), number of hot pixels
NONE , qc_oes1, (0.0234), oddeven column stripe of first raw frame
NONE , qc_oes2, (0.0234), oddeven column stripe of second raw frame
NONE , qc_oes3, (0.0234), oddeven column stripe of third raw frame
NONE , qc_gaf_fpn (2.543), Fixed Pattern Noise of combined frames
qc_darkmed_ave : Average of (3) raw darks medians
qc_darkmed_stdev : STDEV of (3) raw darks medians
qc_ronrms : RMS on Read Out Noise
qc_dark_fpn : Use the window of the MASTER_DARK product frame specified by recipe command line parameters dark-qc_fpn_xmin/xmax/ymin/ymax (default is the whole chip). Take dark-qc_fpn_nsamp (default dark-qc_fpn_nsamp = 100) randomly distributed samples of (2 hsize +1)*(2 hsize +1) (default hsize = 4) sample size from MASTER_DARK. Take median of all sample stdev. This is the isaac RON algorithm applied to a master dark to get the fixed pattern noise.
qc_ron1 : Apply the formulae of DARKFPN to the difference of the first two consecutive raw DARK frames. Convert to NDIT=1 and single raw frame (factor of sqrt(2)).
qc_ron2 As RON1 but for second pair of raw frames.
qc_bpm_method: Bad pixel map method
qc_bpm_nbadpix: All pixels above kappa * sigma, where kappa is --bp_noise-thresh_sigma_fct (default = 10)
qc_oes1, (not calculated by pipeline): Of the first dark raw frame, calculate the median of all odd columns and all even columns for slitlet #25 only and derive stdev. This parameter monitors sporadic occurence of odd-even signal in slitlet #25
qc_oes2, not calculated by pipeline): As qc_oes1, but for second raw frame
qc_oes3, (not calculated by pipeline): As qc_oes1, but for third raw frame
qc_gaf_fpn, (not calculated by pipeline) generate histogram of MASTER_DARK and fit Normal distribution, read stdev.
- slitlet #25 (the #31th slitlet counted from left) might contain additional oddeven signal
- random hot/cold pixels in slitlet #31 (the #18th counted from left)
Reasons for rejection:
- persistence due to previous exposures (objects or standard stars, typically) with high counts (generally about 10,000 ADU).
