Here we present three illustrative cases. For $alpha$ Persei our method allows us to refine the bright end of the membership list, while for Collinder 121 the Hipparcos data change the whole appearance of the association. Finally, we report the discovery of a new association in the field of Cepheus OB2. | | Source: | arXiv, astro-ph/9707088 | | Services: | Forum | Review | PDF | Favorites | |
