Orbital parameters as function of eccentricity for the substellar companion GQ Lupi b around its host star with the colour scale indicating the logarithmic density of solutions. The panels in the left column are reproduced from Ginski et al. (2014b) and they show the 1% best-fitting solutions out of 5 000 000 runs of their LSMC fit. The right-hand panels show the orbital solutions, which are consistent with the radial velocity measurement from this work.
