Normalised cumulative Q(H⁰) as a function of Q(H⁰) for H II regions and stellar associations. The individual galaxies are shown in pastel and the sum of all galaxies is shown in bold colours. We only show the H II regions and associations in the overlapping coverage that do not fall in the centre (corresponding to the sample used in Sect. 3.4). The H II region completeness limit from Santoro et al. (2022), corresponding to a luminosity of 10³⁷ erg s⁻¹ is indicated by the left red dashed line. The two blue lines corresponds to a 10³ M_⊙ and 10⁴ M_⊙ cluster that is 1 Myr old.
