This plot

Trending plots monitoring the number of bad pixels.

The number of bad pixels is derived from flat fields. The monitoring is for the setting with reference wavelength 3218.6 nm since these flats give a stable number of bad pixels. Paranal values are currently not plotted because they differ from QC Garching values due to different pipeline configuration (i.e. different thresholds for bad pixel detection).  


General information

Click on any of the plots to see a close-up version. The latest date is indicated on top of the plot, data points belonging to that date are specially marked.

If configured,

  • 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
