Synopsis of all detected Lyα haloes, presented in two views per object. Each image shows in greyscale the Lyα surface brightness of only the extended halo component, with a model of the continuum-like component subtracted. Left panel in each column: full-size 5″ × 5″ image, smoothed as described in the text, and displayed with fixed SB cuts from −1 to + 20×10^-19 erg s^-1 cm^-2 arcsec^-2 to emphasise the outskirts of the halo and the transition into noise. The scale bar in the lower left indicates a transverse distance of 20 kpc. A model image of the HST counterpart is superposed in red when available. The white square specifies the zoom window. Right panel in each column: zoomed 20 kpc × 20 kpc view of the same object, very slightly smoothed (see text) and with individually adjusted cut levels from 0 to the maximum pixel value, to show the bright inner region of the halo. The dotted circle centred on the object indicates the exponential scale length r_s,h of the Lyα halo. The bar in the lower left shows a distance of 5 kpc. The semitransparent green circle in the lower right represents the FWHM of the MUSE PSF. Superimposed in red are the HST F814W pixel data of the object, with fore- and background sources masked out.
