Disentangled spectra of MWC 656 near quadrature, showing spectral regions where the companion exhibits non-flat continuum features. From left to right, the panels display the HeII [[INLINE113]]4686 emission line, Balmer Hβ, and HeI [[INLINE115]]6678. Observed spectra near quadrature phases are plotted in black (top and bottom rows). The individual Doppler-shifted components of the Be star (pink) and the companion (green), obtained from spectral disentangling, are overplotted together with their summed model (light pink).
