This plot shows the fractional fixed pattern noise derived from the
normalized master flat. In dual beam imaging mode the QC parameter is
monitored for the left and the right beam and for the four two dual beam
filters D_H23 and D_K12 separately.
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
