Fig. C.1.


Top: pseudo 6.25 Å (5 layers) narrow-band map centered at the central wavelength (4872.7 Å) of the 3D mask of the Lyα emission obtained in Sect. 3.2. The map, obtained after PSF and continuum subtraction, shows a 57″ × 57″ (or 438 kpc × 438 kpc) FoV and it is color coded following the Lyα surface brightness. Bottom: χsmth map for the same wavelength range as in the top panel, and obtained using a Gaussian kernel with FWHM = 1.66″ (i.e. similar to the seeing), as explained in Appendix C. To guide the eye, in both panels we overlay a grid spaced by 15″ (or 115 kpc) and we indicate the position of QSO1 and QSO2 prior to their PSF subtraction. In both panels, the interloper galaxy G is indicated with its contour.
