This plot

The population standard deviation of the pixel values of the first input raw bias is computed. This is the combination of structure, fixed pattern noise, and read out noise. The read out noise and the fixed pattern noise contributions are then quadratically subtracted.  


General information

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

If applicable, the latest values from Paranal ops logs are plotted as blue dots. More information about those values, including a download option, is available in the OPSLOG section on top of the page.

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
