Surface rotation distributions in the three selected clusters NGC 2264, NGC 2362 and hPer, as a function of age. The colour codes for the stellar mass (from 1.3 to 1.9 M_⊙). The solid lines are given by evolutionary models of 1.4 (in blue), 1.6 (in green) and 1.8 M_⊙ (in red). The grey coloured areas symbolize the uncertainty on the age of the clusters which is of around 1 Myr. The squares, the triangles and the open circles represent the 20th percentiles, the median, and the 80th percentile of the rotation distributions in each cluster, respectively.
