Mass function of star clusters in our entire suite of clouds calculated as a KDE with an Epanechnikov kernel. From left to right, we show clouds in which we modify the growth of star clusters, their feedback mechanisms, as well as the initial gas surface density of the cloud. The black solid line present in all the panels corresponds to our fiducial cloud, and the thin dashed lines provide a visual representation of d N/d m ∝ m ⁻² between 300 and 10⁴ M _⊙. Star clusters more massive than 10⁴ M _⊙ are shown individually as vertical lines.
