Spectroscopic observation of the transit of WASP-52b. Top: SOPHIE radial velocity measurements as a function of the orbital phase (diamonds), Keplerian fit ignoring the transit (dotted-dashed line), and final fit including the model of the Rossiter-McLaughlin anomaly (dashed line). The vertical dotted lines show the times of mid-transit, first, and fourth contacts. Bottom: residuals of the final fit.
