Additional (see Fig. 2) dynamical spectra of selected circumstellar and photospheric lines (as labeled) of the HR 6819 system, phased with the orbital period (see Table 2) of the inner binary. The individual line profiles are overplotted at the top of each panel, where dashed horizontal lines identify the ranges of the color-coding in the dynamical spectra. Hβ was constructed with dataset B alone (see Table 1) to minimize the effect of the long-term disk variability of the Be star on the appearance of the emission.
