Trending plot for wavelength calibration using Ar arc lamp.
The plot monitors the differences between the calatalogue Ar wavelength
and the wavelength from the dispersion solution for the SC detector
and MEDIUM resolution. There are ten lines in total, split between two plots.
In addition, there is also the RMS of the differences (on plot 1 only).
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
