Notes. Radius ratios as determined from our observations in different filters (Col. 4), the correction that is applied to the radius ratios due to stellar variability (Col. 5), as well as the wavelength-dependent change in radius ratio assuming a background of unocculted starspots that cover 10% of the stellar surface (Col. 6) (note that the difference in i-band is set to 0) (see also Sect. 6.4). The instruments, filters and central wavelengths are indicated in Cols. 1 through 3.
