The CMDs of OBP-near (cyan circles) and Briceño-1 (red circles) stars: the top panel shows the combined CMD of both groups with their combined best-fit isochrone (dotted line); the middle panel shows the CMD of Briceño-1 and its best-fit isochrone; the bottom panel shows the CMD of OBP-near and its best-fit isochrone. The legend in each panel quotes the associated age of the isochrone fit and its uncertainty.
