Dynamic spectra in Hα of AC Her, HD 213985, HD 52961, IRAS06165+3158, IRAS19125+0343, RV Tau, SAO 173329, SU Gem, U Mon. The observed (left) and modelled (right) spectra are paired for each object. The spectra are plotted as a function of orbital phase. The velocity on the x-axis denotes the radial velocity shift from the systemic velocity of the binary system. The spectra are normalised to the continuum flux level. The horizontal dashed line marks the phase of superior conjunction.
