A color–magnitude diagram example of the isochrone set generated from the YREC sample grid. We plot the absolute Gaia DR3 G mag and Gaia DR3 BP–RP. Isochrones (black) were computed using the kiauhoku-generated EEPs derived from the YREC main grid. We adopted solar metallicity for M67 and an age of 3.95 Gyr (C. Reyes et al. 2024), and Fe/H = 0.03 with an age of 0.125 Myr (S. Gossage et al. 2018) for the Pleiades. Data for M67 and the Pleiades were taken from C. Reyes et al. (2024) and M. G. J. van Groeningen et al. (2023), respectively. Isochrones are compared with Pleiades data (bottom panel) and M67 data (top panel).
