Background-subtracted counts map of the MSH 15–52 observations for the energy band 381 GeV–40 TeV. The map was computed for a 0.005° ×0.005° binning and was smoothed with a Gaussian kernel of σ = 0.02° to reduce statistical noise. The 1σ contour of the elliptical Gaussian fitted using ctools is indicated as a red ellipse. The fit results from Aharonian et al. (2005) are indicated as a blue ellipse. The crosses indicate the statistical uncertainty in the centroid positions. The white circle indicates the On region used in the On-Off analysis. Coordinates are for the epoch J2000.
