Notes. Flux is given in erg s-1 cm-2. Measurements on the fuzz around CFHQS J2329-0301 have also been published by Willott et al. (2011), who obtained similar results. No flux has been reported by Bunker et al. (2003) for the flux of the extended Lyα emission surrounding PC 0953+4749, but this object is also part of the CJW06 sample. The flux for the nebula around HS 1449+19 is from Table 3 in Martin et al. (2014a). See text for possible caveats considering the comparability of the presented values on flux and extent.
