This plot

Trending plot for CRIRES RON as determined from DARK exposures.

The read-out noise is measured from the difference of the 3rd and 2nd dark image. The trending shows RON from DIT=1sec and DIT=300sec exposures for all four chips.

 

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
