Notes. ID: GALICS group ID. z: redshift. δ: overdensity factor. Fcat: Total Lyα flux from catalog. Ffil and Fdif: Lyα flux measured in the filaments and the diffuse components. S/Ndif: S/N of diffuse Lyα emission. Sdif: Area of the diffuse component (arcsec2). SBdif: Average surface brightness of the diffuse Lyα emission (10−20 erg s−1 cm−2 arcsec−2). Fdif/Ffil: Fraction of flux in the diffuse component in %. Flux unit are 10−18 erg s−1 cm−2.
