Notes. Preliminary properties of BIND Cepheids. Preliminary orbital and physical properties of three BIND Cepheids with best defined orbits. For two of them periods are fixed to the values obtained from the O−C analysis (marked with asterisk). In the penultimate column period ratios are shown for easy comparison with mass ratios. Note that for SMC-CEP-3674 the period ratio (marked with +) was calculated using for fundamentalization Eq. (2) from Szilàdi et al. (2018). In the last column radii ratios calculated from period-mass-radius relation (Pilecki et al. 2018) are provided.
