Posterior mean of the SN1987A reconstruction. The top panels display on the left the reconstruction of the sky and on the right the separated diffuse emission. The bottom panels display the reconstruction of the point-like emission (left) and a zoom into the reconstruction of the diffuse emission from 30 Doradus C (right) as marked in Fig. 1. We convolve the point sources with an unnormalized Gaussian kernel with standard deviation σ = 0.5, in order to make them visible on printed paper. The different colors represent the logarithmic intensities in the three energy channels 0.2–0.1 keV, 1.0–2.0 keV, and 2.0–4.5 keV and are depicted in red, green, and blue, respectively.
