Notes. 

(a)

Number of photometric measurements used to compute the mean spectroscopic distance.

(b)

Numbers in parentheses are not rms errors but refer to the minimum and maximum values where the distance of a given white dwarf is varying within dspectro ± 1σ.

(c)

Summary of the status of the Hyades membership as discussed in this paper, including the classical members and the new candidates that are still valid candidates or that were rejected as non-members following our analysis. We also identify old white dwarfs for which the age is incompatible with a Hyades origin. Finally, one object has uncertain atmospheric parameters and we can not rule it out as a member. Note that binaries (three classical members, Nos. 1, 4 and 7, and two new candidates, Nos. 12 and 13) are excluded from this table.
