Spectra of the southern extension of the nebula and a close low-redshift interloper. Left-most panel: White-light image of the MUSE data cube around the quasar (at (0, 0) position) prior to subtracting contamination sources. 5 and 10σ contours of the extended Lyα nebula are overlaid. Enclosed by a dashed elliptical contour is the zgal = 0.187 line-emitting galaxy. Other panels: Spectra of the southern portion of the nebula (top row) and the line-emitting galaxy (bottom row) shown in three different wavelength portions covering Hα, Hβ+[O III] and Hγ at zgal, the last of which coincides with Lyα at zquasar = 3.24.
