Fig. 2
Top panels: Lyman-α flux integrated over the whole Lyα line as a function of time for 500-s sub-exposures in visits 1 (circles, left) and 2 (squares, right). The different colours mark the different HST orbits. Bottom panels: Lyman-α flux corrected for the “breathing effect”. Dotted lines show the mean fluxes in visits 1 and 2.
