This plot
This plot shows the median counts of the brightest non-rejected flat used by the detector monitoring recipe.
upper threshold = 47000 ADU: Due to the inhomogenous illumination of the UVB imaging flats, the most illuminated pixel
regions begin to saturate (counts = 65535 ADU) for frames with median counts > 47000 ADU.
lower threshold = 40000 ADU: Sampling smaller flux ranges means covering the linear part of the
detector response curve only. The non-linearity
expressed as a fraction at the reference flux level of 50000 ADU should be based on a flux
range exceeding the 40 000 ADU. Otherwise the linearity QC parameter becomes
more and more a function of the flux range.

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
