Radial velocities of WASP-127b for both transits (respectively blue and orange for the 2019-02-24 and 2019-03-17) phased-folded. The radial velocities have been corrected from the v_syst and the Keplerian model. The vertical dashed line is the mid-transit while the dense vertical dotted lines correspond to t₁ and t₄ and the vertical dotted lines are t₂ and t₃. The horizontal dashed line corresponds to null velocity.
