Residual counts map after subtraction of the fitted celestial background model and smoothing with a 2D Gaussian kernel with σ = 0.4°. Logarithmically-spaced Hα emission contours of the SMC are shown, together with the locations of the currently-known pulsars and SNRs in the galaxy (stars and points respectively). Black circles mark the extent of the 2DG model and the positions of the components of the 3PS model (including in all cases the 2σ uncertainty in the position).
