Projected velocity of a Keplerian disk along the line-of-sight in units of the projected orbital speed at the base of the disk (v_orbsini) vs. the normalized meridian distance (the distance to the stellar rotational axis in stellar radii). The intersection of a horizontal line with the hatched area indicates the range of meridian distances for which the projected velocity occurs. Results for different disk sizes are plotted: R_disk = 10 R_eq, vertically hatched area; 4 R_eq, horizontally hatched area; and, 2 R_eq, diagonally hatched area. The velocities b to d from Figs. 1 and 4 are indicated as horizontal dashed lines. Top: full velocity range; bottom: zoom of the low-velocity components.
