Table A.1

Central wavelength, wavelength range covered by each defined bin, and planet-star radius ratio (R_P ∕R_*) values estimated through the fitting procedure for each wavelength bin using the SKYSUB data set (shown in Fig. 5). We note that a − 0.005 offset has been introduced to the resulting R_P∕R_* values to subtract the average difference with the Santos et al. (2020) values. Each bin contains eight ESPRESSO slices, except the last one, which contains ten. Moreover, it should be noted that this wavelength binning definition does not involve spectral slice overlap, but a slight overlap in wavelength is present between adjacent bins as a consequence of the way orders are created by dispersionplus cross-dispersion, as seen on ESPRESSO and similar echelle spectrographs.
