This plot

Wavelength calibration: trending of dispersion (in 10E-3 nm/pixel).

Dispersion is monitored for the two daily health check settings with reference wavelength (on chip 3) of 1090.4nm using ThAr lamp and 4092.9nm using N2O absorption cell.

Chips 1 and 4 of the 1090.4 nm setting suffer from vignetting. Pipeline results are arbitrary and are not plotted.

Pipeline processing in Garching applies dark subtraction and flat-fielding. This can result in differences for the dispersion. Paranal results for some detectors are, therefore, omitted.  

General information

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