Rotation periods versus (G_BP − G_RP)₀ for cluster members and comparison to models. A19 refers to the model by Amard et al. (2019), where both the sequences for initially slow and fast rotators are shown by solid and dashed lines, respectively. M15 is the model of Matt et al. (2015) with the unsaturated and saturated regimes indicated by solid and dotted lines, respectively. B10 is the model of Barnes & Kim (2010), with the solid and dashed lines again denoting initially slow and fast rotators. S20 is the model of Spada & Lanzafame (2020).
