This plot
Trending plot for the number of bad pixels of the Fringe Tracker (FT) and Science Camera
(SC) detectors. Values are determined from flat-field measurements.
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
