Abstract:
In this paper, relation was established for Hyades stars between their
apparent magnitudes and parallaxes. The precision criteria of this
relation are very satisfactory. The importance of this relation was
illustrated through its usages as: (1) A criterion for membership of
the cluster, (2) a generating function for evaluating some parameters
of the cluster.
