Projected radial velocity profiles for various models. The left filled-in region in each panel denotes the stellar size. Two velocity-distance relations are plotted: 1. Corotation with the stellar surface, where the velocity increases away from the star, and 2. Keplerian rotation for several inclinations, where the velocity increases towards the star. The striped lines present the maximum Hα velocity detected in the disk (in black), determined by the extent of the variability, and the Ha velocity determined by the average of half of the peak-to-peak velocity (in gray).
