Grid of simulated gwIMFs in dependence of the SFR (from left to right: $\psi ={10}^{-5},1,{10}^4{M}_{\odot }{\mathrm{yr}}^{-1}$) and metallicity (from top to bottom: [Z] = 0.2, 0, −3, −5) for the IGIMF-2021 formulation (solid red line) by Yan et al. (2021) using the GalIMF code (Yan et al. 2017) in comparison with the canonical IMF (dashed black) with the power-law indices α = 1.3 for stars in the mass range of 0.08 − 0.5 M_⊙ and α = 2.3 for stars with > 0.5 M_⊙ (Kroupa 2001). The grey solid diagonal lines refer to α = 2.3 for visualization. This grid is similar to Fig. 2 of Jeřábková et al. (2018) but includes only the IGIMF-2021 formulation which is adopted throughout the analysis presented in this study.
