Notes. The S/N was calculated empirically from the residuals on the continuum of transitions approved by our QT. The S/N per frame was calculated in each frame and scaled by the number of pixels per angstrom. On the other hand, the S/N per transit was calculated on the first frame and scaled by the number of pixels in one FWHM and the number of in-transit frames (#in frames at the table). In the binning column, 2s means that we binned two pixels in wavelength, and 4t means that we binned four frames in time. TrES-2b was a special binning case, as we performed a nonuniform time binning. The references for each dataset are listed below.
