[ascl:1307.006] im2shape: Bayesian Galaxy Shape Estimation
im2shape is a Bayesian approach to the problem of accurate measurement of galaxy ellipticities for weak lensing studies, in particular cosmic shear. im2shape parameterizes galaxies as sums of Gaussians, convolved with a psf which is also a sum of Gaussians. The uncertainties in the output parameters are calculated using a Markov Chain Monte Carlo approach.
