Star formation rate estimated assuming the universal Kroupa (2001) IMF (SFRK01) and the corresponding correction factors (KK01 − IGIMF3) used to correct that SFR for the environment-dependent IMF (described by the IGIMF3 model from Jeřábková et al. 2018). Different lines show the dependence of the correction factor on metallicity (represented by [Fe/H]). For example, at log10(SFRK01) = −2 and [Fe/H] = −1, SFRIGIMF3 ≈ 100.6 SFRK01.
