Notes. The orbital phases were obtained using the ephemeris computed in Sect. 4. (a) Number of spectra used for the extraction of the reflected spectrum in Sect. 5. Bracketed numbers indicate the total number of spectra used for the update of the orbital solution in Sect. 4. (b) S/N in the 46th echelle order as computed by the data reduction pipeline (c) Phase range covered by the spectra used to extract the reflected spectrum (Sect. 5).
