WebStars in the cluster NGC 2362 are marked with star symbols. The turnoff for NGC 2362 appears to be at a B-V value of 0.0. Stars in the cluster M68 are marked with solid circles. The main-sequence turnoff for M68 appears to be at a B-V value of about 0.4. Real clusters present a more difficult challenge. WebThe system is the brightest member of the open cluster NGC 2451, over two magnitudes brighter than every other star in the cluster. As the turnoff point of the cluster is currently around B7, the parameters of the system fit with cluster membership.
