Atmospheric refraction effects on the Norris and Keck multiobject spectrographs
Large field spectrographs are severely influenced by atmospheric refraction. We discuss the effect of differential refraction across the field as well as the chromatic effects for the Norris spectrograph under construction for use at Palomar Observatory and for a similar spectrograph for the Keck telescope on Mauna Kea.
