Table 2

Model parameters θ used in the spectroscopic and photometric model of the binary pipeline (see Sects. 3.2.2 and 3.2.3).

Parameter Unit Description Sp. Ph.
Teff[1,2] K Effective temperature
logg[1,2] dex Surface gravity
[Fe∕H] dex Iron abundance
Vr[1,2] km s−1 Radial velocity
vmic[1,2] km s−1 Micro-turbulence
vbroad[1,2] km s−1 Line broadening
R[1,2] R Stellar radius
E(BV) Interstellar reddening
ϖ mas Parallax

ηn Luminosity ratio (see Eq. (9))

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.
