Projected Ω vs. i traces determined via Monte Carlo sampling in radial velocity for the star 4–19. The ranges of the determined physically possible solutions are shown by the gray points, and the exact orbital solutions determined via radial velocity measurements from SINFONI data are indicated by the blue star markers for both the positive z (navy) and negative z (light blue) solutions. The errors in [x, y, z, v_x, v_y] are taken into account by sampling these values from a Gaussian distribution, but the resulting error bars are excluded from the figure. This consideration results in an uncertainty in Ω for the positive z solution of dΩ = 20.7° and dΩ = 15.8° for the negative z solution; for i it is given as di = 6.7° and di = 7.4° for positive and negative z solutions, respectively.
