Notes. (1) The ratio between the uncertainty of Rp∕R⋆ at a given wavelength, assuming a realistic estimate of the noise per spectrophotometric point, compared to an ideal photon noise case. (2) We present all transit depths we measured, but flag some of them with poor data quality (value of 0). These measurements were excluded from further analysis. Specifically, the bluest light curves in B600 are affected by high airmass at the end of the observation. The R150 data near 750 nm and > 850 nm might be affected by O2 and H2 O absorption bands, and we considered them unreliable. Robust transit depth measurements are marked with a data quality value of 1.
