The FlatBlue+1 and FlatBlue+2 lamps are used for imaging screen flats.
The RMS is calculated from the master screen flat image pixel sample (2x2
binning) X: @200 @1800 and Y: @400 @800 covering the unvignetted area
of chip1 and chip2.

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
