From a wavelength calibrated MOS arc lamp exposure, the mean spectral
resolution from all lines in catalog is computed. Each single spectral
resolution is computed as the ratio between the arc lamp line wavelength
and its FWHM. The values trended here are for the 300V grism with a slit
width of 1.0" and the order separation filter GG435.
Data have been acquired using the blue-sensitive EEV 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.
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
