Values of v sin i derived from the oversampled convolution method compared to v_eq. The linear $1\text{:}\frac{4}{\pi }$ relation (dashed line) represents the expected value of sin i for an isotropic distribution of inclination angles (see Appendix B of Ruh et al. 2024). The 1:1 relation with a 10% margin (solid line and shaded region) and the $1\text{:}\frac{1}{\text{2}}$ relation (dotted line) correspond to i = 90° and i = 30°, respectively. The vertical dashed grey line indicates the 2 km s⁻¹ threshold, and the diamond markers correspond to young candidates (Cortés-Contreras et al. 2024).
