$T_{\rm Min~I}$
0.7068 0.7080 0.7081 0.7086
K1(km s-1) 73.9 75.7 74.0 74.2
K2(km s-1) 102.3 105.5 108.1 100.4
K1/K2 0.722 0.718 0.684 0.739

Notes. The period was kept fixed and the epoch of the primary minimum $T_{\rm Min~I}$ is tabulated in HJD-2 450 545. Note that by its principle, KOREL does not provide information on the RV zero point in the solution. The only way to derive the systemic velocities of both components is to measure the individual disentangled line profiles in the classical way - see the text for details.
