Equivalent widths estimated from the detections of Lyα in the individual GLASS spectra of the four main images of the multiple-imaged system at z = 6.1 from Boone et al. (2013) and Balestra et al. (2013) (left part) and the two images of the z = 6.4 Lyα emitter from Vanzella et al. (2014b) (right part) listed in Table 5. The equivalent widths estimated by Balestra et al. (2013) and Vanzella et al. (2014b) are marked by the dotted and dashed lines, respectively. The shaded regions indicate the quoted uncertainties. The gray dots represent GLASS spectra, with severe contamination at the location of Lyα making the GLASS equivalent width estimates only tentative. The arrow indicates that the tentative estimate of MACS0717_00846 at PA = 020 is outside the plotted range. The equivalent width estimates from the GLASS spectra generally agree with each other. There is marginal agreement with the Vanzella et al. (2014b) estimates, whereas the GLASS equivalent widths are generally lower than the estimate from Balestra et al. (2013).
