This plot

Wavelength calibration: trending of resolving power.

The resolvin power (lambda / Delta lambda) is monitored for the daily health check setting with reference wavelength (on chip 3) of 1090.4 nm which uses a ThAr lamp. It is determined from the median of the spectral lines identified on each detector.  


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
