Fig. 2
Donor-subtracted spectra of DQ Vel in the Hα (left panels) and Hβ (right panels) regions around the secondary eclipse. Spectra are shown at the maximum of the long-term cycle (upper panels) and on the way to the minimum of the long-term variability (lower panels). Labels indicate orbital (left) and long cycle (right) phases. The spectra were offset for clarity.
