“…In cases where our groundbased imaging was able to clearly resolve the host, the slit was aligned with the major axis of the galaxy to minimize slit losses (in all cases a 1″ slit was used); otherwise, the parallactic angle (Filippenko 1982) was used. LRIS is equipped with an atmospheric dispersion corrector (Phillips et al 2006), so flux losses associated with nonparallactic angles are minimal. A few systems (PTF 10uhf, PTF 10tpz, PTF 11rks) exhibit large, resolved hosts that cannot be easily accommodated in the slit; both of these systems appear to be special cases and are discussed individually later.…”

“…To date, the only large optics coated with this coating are the two 1.05-m Keck-I Cassegrain ADC prisms 15 , which operates over the range from 0.31-to-1.1 µm. The MgF2 and Al2O3 were deposited on the prisms in the Lick vacuum chamber, then the prisms were transferred to the Strasbaugh table for spin-coating.…”

“…The optical and opto-mechanical feasibility of a large ADC of this type and approximate size (~1m) has been demonstrated by the ADC for the Keck telescope. 3 A detailed optomechanical model of the ADC will be developed in the second half of the MOBIE conceptual design phase.…”
