The four boxes show the counts in the raw frames of the modulation demodulation efficiency calibrations
for
- both detectors (CAM1 and CAM2) and
- both readmodes (S= SlowPolarimetry and F=FastPolarimetry).
The counts in the raw frames are composed of a bias level of ~1000 ADU
plus lamp flux. For every raw frame, the counts are taken in one even row
(pixel area = [60 268 260 268]) and in one odd row (pixel area = [60 269
260 269]). The average over all raw frame planes of the cube is taken,
resulting in a mean odd_row and a mean even_row counts for both detectors.
The maximum between the even_row and odd_row values is taken, for both
cameras separately. The maximum over all raw frames is taken. This QC
parameter is used to check for saturation and under-illumination.

The latest date is indicated on top of the plot.
If configured,
- data points belonging to the latest date are specially marked
- statistical averages are indicated by a solid line, and thresholds by broken lines
- outliers are marked by a red asterisk. They are defined as data points outside the
threshold lines
- "aliens" (= data points outside the plot Y limits) are marked by a red arrow (↑ or ↓)
