Lense-Thirring effect on astrometric (upper plots) and spectroscopic (lower plots) observations of the S2 star, considering a = 0.99 and various Ω′ and i′. The angular momentum direction i′ = 45° and Ω′ = 160° considered for the mock observations are visible on each plot and are denoted with the solid red circles. The different types of curves on each plot correspond to different values of the angle Ω′. For i′ = [0°,180°], we obtain the same curves whatever Ω′ for the astrometry but they are different when considering the spectroscopy: thin and thick lines correspond to i′ = 180° and i′ = 0°, respectively. On the other plots, solid, dotted, dashed and dash-dot-dotted curves correspond to Ω′ equal to 0°, 45°, 90° and 135°, respectively. Open circles on all plots denote the position of the apocenter and open triangles denote the pericenter passages.
