Gaia CMD of WD candidates with probabilities of OC membership from the 5D, 3D, or Hunt & Reffert (2023) analysis ≥0.5. The objects selected for the subsequent analysis are marked in red. The error bars are omitted for clarity. The dashed black lines represent the cooling curves for 0.4 and 1.2 M_⊙ DA WDs from Bédard et al. (2020), and the dashed red line indicates the preselection cut employed in Sect. 2. The 4.3 Gyr cooling age isochrone seen in Fig. 1 is outside the bounds of the figure. Discarded objects (in black) lying outside of the region delineated by the 0.4 M_⊙ cooling curve and the 4.3 Gyr cooling age isochrone are not considered in the subsequent analysis.
