The Loktin-Matkin catalogue determines distance and red shift data for 330 of them from UBV, and the Markarian and Collinder catalogues list some of their aberrant members, such as Ap and Am-type stars, which have compositions that vary from their other members, which have constant lithium-beryllium ratios. The Shapley Classification assigns them values of c through g according to their concentration, while the Trumpler schema adds range and brightness to their description. Another technique uses main sequence fitting for distance measuring between them, which applies parallax data from the satellite Hipparcos to an example near Aldebaran. Co

Containing between 50 and 1000 young stars which lie within the galactic plane, the classical illustration contains such members as Taygeta, Celaeno, and Alcyone. FTP, name this type of loosely-bound astronomical body originating in diffuse nebulae including the Pleiades, the opposite of a globular cluster.
