Notes.
Stellar masses and star-formation rates (SFRs) taken from Marasco et al. (2023) reported to the distances used here;
López-Sánchez et al. (2012). For NGC 5253, we have adopted O/H for HII-region A since it is closer to the brightest SSC, and more consistent with the previous determination by Kobulnicky et al. (1997) of 12+log(O/H) = 8.16.
