% Fit a 2D gaussian to a star image Calculate a histogram of the pixels and fit a 2D Gaussian. 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] = FitStarHist( pixels, x0, doPlot ) -------------------------------------------------------------------------- ------ Inputs ------ pixels (:,:) Pixels x0 (2,1) Center doPlot (1,1) If true, plot ------ Outputs ------ xfit (2,1) Gaussian center sigma (2,1) Standard deviation height (2,1) Height iter (1,1) Number of iterations in the Newton-Gauss method -------------------------------------------------------------------------- Copyright (c) 2018 Princeton Satellite Systems, Inc.
