This plot

The bias level (in ADU) is evaluated as the median value of all pixels in the first raw bias in the input set-of-frames. The trending is done for 2x2 binning only.  


General information

Click on any of the plots to see a close-up version.

If applicable, the 20 latest values from Paranal ops logs are plotted as blue dots.

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
