Comparison between masses for stars in the CrA complex and spectral types (from Esplin & Luhman 2022). Filled blue symbols are for stars in CrA-Main; open red symbols for those in CrA-North. The black line is the relation for old stars by Pecaut & Mamajek (2013); blue and red lines are the relations appropriate to Baraffe et al. (2015) isochrones of 3 and 8 Myr, respectively. The upper panel is for all stars; the lower panel is a blow-up on lower mass stars.
