Fig. 2


Probability of cluster membership as a function of RV for open clusters NGC 2516, NGC 2547 and NGC 2264 derived from the maximum likelihood fit of a double quasi-Gaussian distribution to the data in Fig. 1. Black crosses show probabilities for slower rotators (v sin i ≤ 5 km s-1), red triangles show probabilities for faster rotators. Estimated values of the mean velocity, and dispersion σc of the cluster population are shown on the plots.
