Hyades members distances
Listed in IVOA Registry (Virtual Observatory)
Distances for 145 Hyades members in an extended region of the Hyades cluster were derived on the basis of new, highly accurate proper motions obtained from work on the catalogues FK5 and PPM.
Description
The cluster membership on the stars has been discussed and a few new candidates are proposed. From a selected subset of our sample we have obtained the convergence point {alpha}=6h30.7m+/-1.7m=97deg41'+/-25', {delta}=5deg59'+/-11'.
Combining this point with the mean cluster radial velocity of 39.1km/s by Detweiler et al. (1984AJ.....89.1038D) one find the galactic space velocity (U, V, W)=(-42.02, -20.12, -1.04)km/s. The galactic coordinates of the centre of our sample are (X, Y, Z)=(-44.3, +0.5, -18.2)pc. The distance of this centre from the Sun is 47.9+/-0.8pc corresponding to a modulus m-M=3.40+/-0.04mag.

Individual distance moduli, coordinates and velocity residuals per star are given. The Hyades main sequence has been constructed in the range B-V<1.2mag and it is presented analytically as well as by tabular values. The dispersion {sigma}(M_v_)=0.14mag of the absolute magnitudes about the main sequence indicates its high internal accuracy.
