Notes. WD masses (M_WD), cooling ages (t_cool), and progenitor masses (M_i) have been calculated in Sect. 4. P_max represents the maximum value of astrometric membership probability from P_3D, P_5D, and P_HR.

^(a)

Mentioned in Richer et al. (2021) but no M_i calculated,

^(b)

possible double degenerate system (Williams et al. 2015),

^(c)

radial velocity possibly inconsistent with OC membership (Williams et al. 2015),

^(d)

approximate parameters derived also in Prišegen et al. (2021) using the GDR2 data.
