Notes. Indices 1 and 2 denote the primary and secondary star in the binary system. The line broadening parameter incorporates the effects of stellar rotation and macro-turbulence (see Buder et al. 2018). Columns Sp. and Ph. indicate whether a parameter is included in the spectroscopic or photometric model, respectively.
