Counts map (a) and best-fit model map (b) for MSH 15−52, in equatorial coordinates (J2000). Results derived with the 3D likelihood analysis with ctools using an excess template as source model are displayed. The maps have been integrated over all energy bins contributing to the fit and smoothed using a Gaussian kernel with a width of 0.08°. The small panels show projections onto the two spatial axes; the separate components are indicated as well here.
