This plot

Trending plots 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). QC parameters from darks are only plotted for SC DITs of 0.3 sec and FT DITs of 0.00085 sec, respectively. For the dark level, only darks taken together with the P2VM calibrations are selected. These have FDDL WINDOW = 0.1 (only available since 2019-05-01 in the database).  

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
