The master bias is averaged along its columns. Then the rms of the
resulting 1-dimensional frame is used to check for the presence of a
bias pattern (predominantly in low gain, 2x2 readout) Details can be
found in the plot
tutorial.

General information
Click on any of the plots to see a close-up version.
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 ↓)
- you can download the data for each parameter set if the 'Data downloads' link shows up
