9.1.3
Quality control
The pipeline computes the non linear coefficients, the number of non linear pixels per grating, the detector gain.
Detector non linearity
The detector non linearity is computed as described in 10.1.3. The computed coeffi-
cients are QC.BP-MAP.LINi.MED (i=0,1,2).
A different method is applied to determine the same quantity as described in 10.1.3. The computed coefficients
are QC.BP-MAP.LINi.MEAN (i=0,1,2).
Non linear bad pixels
The pipeline computes the number of non linear bad pixels. Those are given by
QC.BP-MAP.NBADPIX and are obtained with the method QC.BP-MAP.METHOD.
Detector gain
The detector gain is computed as described in 10.1.5 and is given by the value of QC.GAIN.

si_rec_mdark
The recipe si_rec_mdark generates a master dark from a set of raw darks by stacking frames with rejection of
outliers. It also generates a bad pixel map flagging the hot-current pixels.
