QC parameter is derived from each detector of the monthly acquired detector mmoitor template.
Keep in mind, that purpose of this plot is montoring only. The actual gain values are unreliable.

QC1 DB: qc_gain
Description:
Photon transfer curve analysis.
Setup:
INS.FILT1.NAME=Ks
These plots describe:
Fig. 1. chip4: The QC parameter for chip #4.
Fig. 2. chip3: The QC parameter for chip #3.
Fig. 3. Average: The QC parameter averaged over all detectors.
This view is sensitive to common changes.
Fig. 4. chip1: The QC parameter for chip #1.
Fig. 5. chip2: The QC parameter for chip #2.
Fig. 6. Scatter View: The standard deviation of the QC parameter, obtained from the sample of all detectors.
This view is sensitive changes of individual detectors.
Note that the used definition of units are (following DICD):
