𝐶=2455431.0 days. Results inferred from an analysis of a new transit of WASP-10b covered by three filters. The final column tabulates results from TAP’s multicurve MCMC algorithm in which the system parameters of the three separate light curves are locked together and filter-specific parameters evolve independently. The increased significance of the derived parameters is clear. All analyses are consistent with each other and with the results from [31] (Table 1). For all analyses, orbital period (𝑃=3.0927616 days) and eccentricity parameters (𝑒=0.051, 𝜔=2.67 radians) were locked to values derived by [31] using RV data from [37].
