Notes. The listed parameters are orbital period P, sum and ratio of the fractional radii (Rp + R)/a, (Rp/R), orbital inclination i, semi-major axis a scaled by stellar radius R, impact parameter b, total duration of the transit from the first to the fourth contact T14, reference time of the ephemeris T0 (time standard is barycentric Julian Date calculated from UTC times: BJDUTC), the linear and quadratic LD parameters u1 and u2, the average stellar density ρ/ρ.
