% Finds the centroid given intensities on n pixels and their coordinates. This uses the point spread function method. Type StarCentroid for a demo which will draw the centroid and the intensity map. Since version 11. -------------------------------------------------------------------------- Form: [x0, y0] = StarCentroid( i, x, y ) -------------------------------------------------------------------------- ------ Inputs ------ i (1,:) Intensity x (1,:) x coordinate y (1,:) y coordinate ------- Outputs ------- x0 (1,1) x centroid y0 (1,1) y centroid -------------------------------------------------------------------------- Reference: C. Fosu, G. W. Hein, B. Eissfeller, "Determination of Centroid of CCD Star Images," ISPRS XXXV Congress. --------------------------------------------------------------------------
