Comparison between rotational distribution in young clusters and rotation period range at 1 Myr of our fast and slow-rotating models (blue area). The diamonds, left-pointing triangles, and right-pointing triangles are the 50th, 5th, and 95th percentile of the rotational distribution for the respective cluster. The mean values of the 95th (5th) percentiles are indicated by the vertical dashed (dotted) line. See text for references.
