From a wavelength calibrated LSS arc lamp exposure, the mean spectral
resolution from all lines in the 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 blue sensitive EEV
detector, the 300V grism with no filter and a slit width of 0.29".

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 ↓)
