Optimally sampled galaxy-wide IMFs for different SFRs. The unit of ξ_OSGIMF is the number of stars per linear mass interval. The black histogram is the entire stellar sample in the galaxy formed in a 10 Myr epoch. The large scatter in the upper left panel and the serrated feature around log ₁₀(m/M_⊙) = 0 for every panel is explained in the text. The red, green, and blue histograms, comprising our decomposition plot, are the OSGIMFs counting only the first, second, and third most massive stars of embedded clusters. A spoon feature appears at the high mass end of the red, green, and blue curves. The stellar mass distribution is saturated at the high mass end because of the 150 M_⊙ limit. The thin smooth curves are the IGIMFs as in Fig. 3, calculated by Eq. (1) and normalized to give the mass in stars when integrated over the relevant stellar mass ranges.
