Abstract

Raven is a MOAO demonstrator that will be used on the Subaru telescope and will hopefully serve as a pathfinder for future ELT MOAO instruments. In this paper, we present trade studies and the resultant error budget that were used to define the AO architecture for Raven. In particular, we focus here on recent simulations of Raven performance for real science targets, and performance as a function of wavelength, zenith angle and atmospheric conditions. We show that Raven should achieve 30% ensquared energy within 140 mas under median conditions under realistic observing conditions.
