Rotational velocity distributions as a function of absolute G magnitude. The BSSs in OCs reported by Li et al. (2023) are plotted as triangles, while BS_Li23 is marked as a red triangle. BSSs in GCs from Ferraro et al. (2023a) are denoted by gray dots. The v sin i errors for blue triangles, red triangles, and gray dots are from Gaia DR3, Sect. 2.2 of this work, and Ferraro et al. (2023a), respectively. Distance module and reddening for BSSs in GCs are all from the website (https://people.smp.uq.edu.au/HolgerBaumgardt/globular), while those for BSSs in OCs are from Li et al. (2023).
