| Abstract: | 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°. |
