Near-IR and optical color-magnitude diagrams of classified sources. We show the locations of classified targets with Spitzer IRAC photometry for NGC 6822 (top left) and IC 10 (top right) and with Gaia photometry for NGC 6822 (bottom left) and IC 10 (bottom right). The dashed lines indicate the priority criteria from Bonanos et al. (2024). IC10-52406 is the only RSG that shows no IR excess, as it was a serendipitous observation.
