Tentative orbital solution of Schulte 12 for a fixed orbital period of 107.99 d (middle column of Table 4). The average velocities of Mg II and Fe II emissions in the Carmenes dataset are shown by blue dots and the Hermes velocities of Fe II λ 7513 Å (not used to obtain the orbital solution) by open red squares. We note that the phase used here corresponds to the binary ephemeris (Table 4), not to the X-ray ephemeris used for Figs. 2 and 3.
