Notes. V100sin(i) is the projected rotation velocity, ΔV is the total line width, T100 is the excitation temperature, and vturb the turbulent velocity dispersion, all at 100 au and each with their corresponding exponent. The parameters not fit for were calculated using Eq. (3). For M⋆ = 0.69 M⊙, the measured V100sin(i) indicates i = 5.96 ± 0.03.
