NGC 2818A CMD. Padova theoretical isochrones overplotted to our cluster Gaia DR3 CMD for stars within 225 arcsec from the cluster apparent centre. The orange points represent the stars with a cluster membership probability of ≥90% (van Groeningen et al. 2023). The green isochrone reflects the error weighted average of literature values and Gaia DR3 distance (age = 1077 Myr, E(B − V) = 0.18, distance = 3.30 kpc, iron abundance [Fe/H] = −0.29), while the blue isochrone is the model that best fits to our high probability membership data (age = 955 Myr, E(B − V) = 0.18, distance = 3.30 kpc, iron abundance [Fe/H] = −0.024). The red dot shows the position of the identified CSPN, located well within the white dwarf region of the cluster as expected.
