The Adaptive Optics Point Spread Function from Keck and Gemini

Abstract

From analyzing adaptive optics (AO) images of stars obtained at Keck (10 m telescope) and Gemini North (8 m telescope) Observatories, we verify that in general, the AO point spread function (PSF) can be modeled as a Lorentzian or a Lorentzian plus an Airy. However, an additional Gaussian component in the Gemini PSF is associated with an observed degraded AO performance.
