Tomographies in the stellar reference frame for the hydrogen Balmer lines. Top panels: raw tomographies before the RME+CLV correction. Top row, left to right: Hα, Hβ, and Hγ; bottom row, left to right: Hδ, Hϵ, and Hζ. The planetary atmospheric absorption can be distinguished as a darker region following the expected planetary radial velocity profile, and the RME as a brighter feature. We also show the planetary radial velocity profile during out-of-transit with a magenta line. The contact points are represented with dashed and continuous white lines. Middle panels: model tomography computed in the manner explained in Section 3. Bottom panels: corrected tomography obtained by dividing the raw one by the model one.
