Radial velocities of CoRoT-11 measured with the HIRES spectrograph around the transit that occurred on July 1, 2010. The left panel shows all the RV data and the right panel shows a magnification on the transit. The dashed line shows the Keplerian fit without transit. The solid line shows the Rossiter-McLaughlin anomaly fit for λ = 0°. The vertical dotted lines show the transit first contact, mid-time, and fourth contact. The data have been arbitrarily shifted to the systemic radial velocity of V_r =  − 1.229 ± 0.041 km s^-1 (horizontal dotted line), as derived from the HARPS/EGGS data-set only.
