This plot

Trending plot for the number of pixels on the detector of the acquisition camera that have 0 value.

Typically, not more than 6% of all pixels have 0 ADU in a dark exposure; they are potentially not responding.

Note that as of 2017-03-24 not all pixels of the acquisition detector are saved. The image has a size of 1000x1000 instead of 2048x1536.  


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
