Radial distribution of modelled flux contributions for a theoretical observer (white circle) from ²⁶Al (top) and ⁶⁰Fe (bottom) decay. Each column represents average results of 500 model instantiations based on the density profiles GM00–GM04 (grey boxes). The models shown are stellar evolution models LC06, explodability S09, IMF K01, and SFR = 4 M_⊙ yr⁻¹. The latter corresponds to a total mass of 1.8 ± 0.2 M_⊙ and 4.2 ± 0.2 M_⊙ of ²⁶Al and ⁶⁰Fe, respectively. Adaptive spatial binning (Cappellari & Copin 2003) is used to obtain Voronoi tessellations as spatial bins, each of which contribute a flux of 10⁻⁶ ph cm⁻² s⁻¹ for the observer. The colour scale refers to the collecting area covered by each such pixel.
