Figure 4: A comparison of radial-velocity curves of the primary and secondary measured directly in SPEFO (upper panel) and based on KOREL disentangling (bottom panel). Filled symbols refer to the primary and the Crimean spectra are shown by circles, and the DAO spectra by triangles. The final ephemeris (2) was used. |

Figure 5: He I 6678 line profiles of primary and secondary disentangled via KOREL (solid lines) are compared with synthetic LTE line profiles shifted for the systemic velocity of -19 km s-1 and rotationally broadened to projected rotational velocities of 132 and 104 km s-1, for the primary and secondary, respectively, which correspond to spin-orbit synchronization. Wavelengths are in Å and the disentangled profiles from KOREL were normalized using the luminosity ratio from the V light-curve solution - see the text for details. |
