Fig. 15
HERMES spectroscopy of HD 188209 covering some 870 days of monitoring during four epochs. The centroid velocity is shown for all available spectral lines except Hα. The colour coding is the same as in Fig. 12. For visibility purposes, the values for each spectral line were shifted in time with multiples of 12 d, Hβ in black representing the true HJD.
