Notes. References for the cumulative cluster numbers within a 2 Mpc radius that will be observable by MICADO at the ELT. Star formation rate estimates are based on the integrated galaxy Hα fluxes from Karachentsev et al. (2013) and were used to estimate the true number of open clusters contained in each galaxy (see main text). The Milky Way clusters were taken from the HEASARC Milky Way Star Cluster catalogue (Kharchenko et al. 2013) and filtered to include only clusters visible to MICADO at the ELT (i.e., −85 < Dec < +35 deg).
