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 red sensitive MIT detector, the 300V grism with no filter and a slit width of 0.29". On 2018-08-28 new pipeline (v.5.3.35) was introduced. The method of calculating spectral resolution changed and the new values are significantly lower.
