Lyman-α fluxes for 300 s exposures integrated over the entire line and phase-folded on the HST orbital period. The dashed lines correspond to the best fit for the F_corr function. Since the contribution of the breathing effect f_breath to this fit is the same at a given HST phase, the best estimation for the intrinsic stellar flux in each orbit F_nom can be read at phase = 0 (see Eq. (1)). The color code is the same as in Fig. 1, and Visits 1, 2, and 3 are displayed from top to bottom.
