This plot

Wavelength calibration: trending of central wavelength (averages).

This plot uses the average of the central wavelength on the four detectors and the corresponding rms. The values are plotted vs. time. Historical plots show also trending vs. grating temperature (header key INS.TEMP4.VAL). Averages are only available for Garching values. Monitoring is for N2O absorption cell measurements with 4092.9 nm reference wavelength.  


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
