Notes. In each visit, the upper subpanel corresponds to the blue wing of the line, the lower subpanel to the red wing. N/D indicates that no variations were found above 2σ from the reference spectrum of the visit. Spectral ranges are given as velocities in the star rest frame (km s-1), and flux variations are in erg s-1 cm-2 Å-1.
