Fig. 6.


Same as Fig. 5 for Cyg OB2-5 and the 4550–4700 Å region (all plots are offset by 0.2 continuum units with respect to the adjacent ones). Note that in this case there is a small phase difference between the GOSSS and LiLiMaRlin epochs for the A orbit. As the magnitude difference between A and B is larger than for HD 191 201 here the signature of the B component is much harder to detect in the spatially unresolved spectra.
