Notes. The number of pixels and wavelength ranges are those in the final trimmed spectra for public release. The blocking filter OG530 is used only (and always) for Gr#16. The spectral resolution R is given at the central wavelength, as is the velocity resolution V. The FWHM is the full-width-half-maximum of a Gaussian fit to either the [O i] 5577 Å or 6300 Å night sky line, for a 0 slit. The respective values when a 1.5 slit is used can be determined by simply multiplying the values by 1.5. The column headed Arclines indicates the number of lines used. The rms is the typical residual for the wavelength calibration solution.
