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
