Notes. The lower part displays derived (calculated) with fixed quantities indicated. The eclipse duration T14 was calculated from Winn (2010) and depends on the stellar radius among other parameters. The reduced χ2 for both data sets is ≈1.0. Uncertainties are 1σ (68.3%) confidence intervals chosen to be the larger from MC or RP-PB simulations. The eccentricity assumes e sin ω = 0.0. The period agrees with the ephemeris period in Eq. (1) at a 0.30σ level.
