Contribution to the Lyα SB profiles from clustered and undetected LAEs with log(L_min/[erg s⁻¹]) = 38.5. Differently colored lines correspond to a different assumption for the clustering of undetected LAEs. Detected galaxies are assumed to cluster like those in the MUSE-Wide sample. The data points correspond to the modified stacking experiment of individual LAEs of Wisotzki et al. (2018; see Sects. 2 and 4.4). The triangle denotes an upper limit. We employ a pseudo-NB width of 600 km s⁻¹ and the Lyα LF of Herenz et al. (2019). The shaded gray region shows the typical virial radius of MUSE-Wide LAEs.
