(b)Spitzer m3.6 and m4.5 data have a mean error of 0.04 mag. J, Ks photometry for sources in NGC 6822 and WLM is from the Vista Hemisphere Survey DR5 (McMahon et al. 2013) and 2MASS (Skrutskie et al. 2006) for our IC 10 sources. Mean errors in both bands are 0.05 mag. Gaia DR3 G, GBP, GRP photometry data have a mean error of 0.01, 0.07 and 0.03 mag, respectively. (c)See Sect. 3.1.
