This file summarizes several instrument-specific settings that are related to the NOT/ALFOSC spectrograph.
Currently only grisms 3, 4, 5, 7, 8, 10, 11 17, 18, 19 and 20 have full template solutions.
Grisms 10 and 11 are very low-resolution and only occupy part of the detector. Depending on the window used, it may be useful to set the find_min_max parameter to some suitable range, e.g.,
[reduce]
[[findobj]]
find_min_max = [0,680]
Furthermore, grisms 10 and 11 are so low resolution that the rms of the wavelength solution is often quite poor (roughly 0.2 pixels).
For vertical slits, the spectrograph class not_alfosc_vert should be used.
