Notes. (a) Morphological types, galaxy major axis diameters (the blue isophotal values), and Galactic latitudes are taken from the NASA/IPAC Extragalactic Database (NED);1 the major diameters in parentheses are from Jarrett et al. (2019). (b) Distance determinations: Holmberg II TRGB (Sabbi et al. 2018); IC 10 TRGB (Gerbrandt et al. 2015); IC 342 TRGB (Wu et al. 2014); NGC 2403 TRGB (Radburn-Smith et al. 2011); NGC 6744 TRGB (Sabbi et al. 2018); and NGC 6822 CMD (Fusco et al. 2012). (c) Foreground AV extinction values are calculated as described in Sect. 4.1, based on the Schlafly & Finkbeiner (2011) determinations. (d) Metallicity determinations: Holmberg II, IC 10, IC 342, NGC 2403, and NGC 6744 (Pilyugin et al. 2014); and NGC 6822 (Lee et al. 2006). (e)Taken from Nersesian et al. (2019), except for NGC 6744 from Leroy et al. (2021). All estimates use a similar technique, namely SED fitting with CIGALE (Boquien et al. 2019). Distance-dependent quantities (M,) have been reported using the distances given here.
