Probability density distribution of projected rotational velocities for metallicities Z = Z_⊙ (Galactic, green curve), Z = 0.5 Z_⊙ (LMC, red curve), and Z = 0.2 Z_⊙ (SMC, blue curve). The subplots in the top and bottom show the effect of metallicity with the peak of vsini distribution/most probable velocity and the fraction of stars with vsini higher than 200 km s⁻¹, respectively. The Galactic, LMC and, SMC samples are represented using green, red, and blue dots, respectively. Our SMC (this work) and LMC (Ramachandran et al. 2018a) samples are shown as enlarged dots. See Sect. 4.1 for further information.
