Scientific paper

A simultaneous, maximum-likelihood determination of the distance and kinematic parameters of the Pleiades is made. The results are: distance of the cluster d = 135.56±0.72 pc, dispersion σd = 7.66±0.80 pc; space velocity V = 25.94±0.13 km/s, dispersion σv = 0.58±0.09 km/s; coordinates of the convergent point A = 101.95°±0.47°, D = -41.36°±0.29°.
