Scientific paper

A feature of the GLAST-LAT point spread function (PSF), as determined by Monte Carlo studies, and verified with particle beams, is that the projected distributions are not Gaussian, but have power-law tails. Also, widths vary according to a power of the gamma energy. The optimum statistical precision is obtained with a maximum likelihood fit, which is not equivalent to a weighted mean. Also, the maximum likelihood calculation can be much simpler than that used to define the spectrum, since only the part that depends on the source position is relevant. We illustrate these points, and provide estimates of the localization for various sources.
