Computational Developments for Moving Clusters with Application to Hyades

In this paper, computational developments for the parameters of moving clusters are established together with their error estimates in closed analytical forms and applied to Hyades cluster. The data used are 60 stars selected from Schwan (1991). The symbols denote the right ascension (a), declination (δ), proper motion [(μα, μδ)], position angle (θ), angular distance (λ), velocity (V), parallax (p), magnitude (M), helioc. coord. (x c , yC z c), and the distance (d).
