Notes. ga is the number of the parameters used for the description of a LC, ρ = δphen/δphys, where δphen and δphys are the uncertainties in the determination of the zero phase time according to phenomenological and physical models. The used optimum LC model: . EB types: OC – overcontact; C – contact; SD – semidetached; D – detached, P is the period, r1,r2 are the relative radii of the components, Teff1,Teff2, their effective temperature, i is the orbit inclination. The parameters were taken from authors cited in Sect. 4.3.
