This plot

Here we show various parameters for NIR dark frames: median level and rms of the master dark, the cosmic ray hit rate (per second and unit area), and the amplitude of the fixed pattern divided by the dark_med value.

Since 2013-05-05, pipeline xsh_2.2.0 is in operation with an improved calculation of the relative fixed pattern noise.

The newly calculated fpn_norm parameter is approximatly dark_rms / dark_med. Therefore monitoring dark_rms will become obsolete. The read out noise will be monitored instead.

For more information see the plot tutorial page.  


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 OPS column.

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
