Notes. Teff denotes the effective temperature; log g, logarithm of surface gravity; v sin i, projected rotational velocity; Z, metallicity; LR, relative luminosity; 
, the reduced value of χ2 (divided by the degrees of freedom), and (f)indicates the fixed parameter. For comparison with previous results, the values from Shenar et al. (2015) are shown in grey. In the case of Aa1 and Ab components, the results are usually in agreement within the uncertainties. More significant differences are for the Aa2 component; however, our values for the secondary are constrained by the disentangled spectra and mass ratio from KOREL. The uncertainties of the parameters are given in concise form in brackets.
