Left: angle-averaged integrated spectrum of our blob (in black), divided into an extragalactic component (in red) and galactic emission (in blue). Middle: IGM transmission function from R_vir to the observer, fitting the results of Laursen et al. at z = 2.5 (dotted line), z = 3 (solid line) and z = 3.5 (dashed line). Right: resulting spectrum after transmission through the IGM. For all three panels, the vertical line denotes the Lyα wavelength.
