Left: best-fit extended source from 300 MeV to 300 GeV for a uniform disk hypothesis (green) and a 2D symmetric Gaussian (red), plotted in the MOST radio image. The crosses are the centroid uncertainties (1σ), the solid circles correspond to the r₆₈ of the uniform disk, and the Gaussian template and the shaded areas are the 1σ error on size. The putative position of the pulsar is represented by a diamond. Right: bestfit Gaussian or point source in five energy bands. The crosses are the centroid and the position uncertainties (1σ). If the source is significantly extended (see Fig. 5), the r₆₈ of the Gaussian is depicted by a solid circle with the associated errors (shaded areas), otherwise the best-fit point source is represented.
