Detection limits versus stellar inclination for the correlation-based (four top panels) and the LPA (four bottom panels) methods. The detection limits are displayed for different samplings and for different noise levels (black: no added noise, red: 0.01 m s^-1 noise, green: 0.05 m s^-1 noise and blue: 0.1 m s^-1 noise). Solid line: detection limits computed in case 2. Dashed line: detection limits computed in case 1.
