Notes. The 95% upper limits on the EW of an in-transit absorption signal as a function of SYSREM iterations (#) for the Hα line in bands covering 1, 2, and 8 times the FWHM of a narrow line centered on the nominal wavelength in the planetary frame along with the standard deviation (σ) of the transmission spectrum and the reconstructed zeroth iteration values (0*).
