This plot

The upper boxes show the relation between the signal-to-noise ratio and the counts (the signal). The values are derived from telluric standard stars acquired in slit mode. The values are extracted from different wavelength regions known to be free of telluric features.

The lower boxes show the relation between the isquere of the signal-to-noise ratio and the counts (the signal). This is to show deviation from the square root law.

 

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
