% Fit a 2D Moffat PSF to a star image Calculate a histogram of the pixels and fit a 2D Moffat. The height of the marginal distributions, that is the sum along each coordinate, is related to the height of the circular distribution by 1/sqrt(2*pi). -------------------------------------------------------------------------- Form: [xfit,sigma,height,iter] = FitStarMoffat( pixels, x0 ) -------------------------------------------------------------------------- ------ Inputs ------ pixels (:,:) Pixels x0 (2,1) Center ------ Outputs ------ xfit (2,1) Gaussian center rho (2,1) Radial parameter height (2,1) Height iter Number of iterations in the Newton-Gauss method -------------------------------------------------------------------------- Copyright (c) 2018 Princeton Satellite Systems, Inc.
