Synthetic populations of stars obtained by adding five clusters (computed with SYCLIST, Georgy et al. 2014a), each of 10 000 stars at solar metallicity with a turn off mass around 15 M_⊙. The stellar models are from Georgy et al. (2013). These models have the same physic inputs as the one used for computing our moderate angular momentum transport models with an α = 0.1. The range of ages spanned by the five clusters is indicated in the left panel. A noise of ±0.1 dex is considered in log(g). An initial distribution of rotations as given by Huang et al. (2010) is used. The left panel shows a population with the log(g) limit determined for our 15 M_⊙ model with α_ov = 0.1. The right panel shows the same population but this time the correction for the angle of view is not applied on log(g).
