Radial-velocity curve for the final solution (top panel) and the O − C residuals from it (bottom panel). RVs are emission-line RVs, the mean of Hβ and Hγ from the Ann Arbor photographic spectra by Losh (1932) (shown by pluses), and Hα emission wings for all CCD spectra (shown as black circles). The IUE spectra of the compact secondary, published by Wang et al. (2018), are shown by red circles.
