Color–magnitude diagrams for stars in the CrA-complex. The top panels show the (G, BP – RP) magnitudes and colors for Main and North, respectively. The bottom panels show the (H, G – H) magnitudes and colors. Filled symbols are for stars used for the age-dating of the CrA-Main and North groups, open symbols are all the other stars. Overimposed are the isochrones from Baraffe et al. (2015) for different ages, and the main sequence by Pecaut & Mamajek (2013), which is representative of an old population. We marked with purple crosses the stars with apparent G-magnitude >20, which we define as Old/Faint stars, and with blue asterisks the stars that lie closer to the main sequence from Pecaut & Mamajek (2013) than to the 10 Myr isochrone from Baraffe et al. (2015), identified as Old.
