Bayesian Galaxy Shape Measurement for Weak Lensing Surveys-II . Application to Simulations

Abstract

In this paper we extend the Bayesian model fitting shape measurement method presented in Miller et al. (2007) and use the method to estimate the shear from the Shear TEsting Programme simulations (STEP). The method uses a fast model fitting algorithm which uses realistic galaxy profiles and analytically marginalises over the position and amplitude of the… (More)
