Detrending fits for the ground-based photometry. The top plots display the fits obtained for EulerCam and SAAO when detrending with polynomials in sky and airmass. The bottom plot displays the posterior distributions of these detrending parameters along with p = R_p/R_*, which shows the planet radius is not correlated these parameters. We obtained a similar planet radius of R_p = 1.00 ± 0.04 R_Jup with this fit that was within the uncertainites of the planet radius derived without detrending and this value used for the final model.
