This plot
Trending plot for dark exposures of the Fringe Tracker (FT) and Science Camera
(SC) detectors. Plotted are the dark level (FT), the bias level (SC),
and the RMS of the master darks (both). The dark level is determined from the
master dark whereas the bias is determined from the input raw frames and
subtracted when creating the master in case of the SC detector.
The SC detector features a windowed read-out that depends on the spectral
resolution (low, medium, or high) and on the polarimetry mode (splitted or
combined). This plot shows QC parameters from darks with the read-out for
HIGH resolution data. DITs are 0.3 sec (SC) and 0.00085 sec (FT),
respectively.

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
