UVES RV of OGLE-2011-BLG-0417 (dots) with the predicted model from Shin et al. (2012) and Gould et al. (2013; black line). The systemic was fixed to the median value of the observations. The best-fit model which departs from the prediction by 3.7 sigma, is superimposed in grey. The observations reject the modelled Keplerian at a level greater than 2 × 10^-7 (see text). The insert is an enlargement around the observations.
