Notes. RID: ID in Rafelski et al. (2015), rin: inner radius for the test defined in Sect. 3.1, rCoG: curve of growth radius used as the outer radius for the test (Sect. 3.2), S/N(rin − rCoG): S/N of the flux measured at r = rin − rCoG (halo candidates have a S/N(rin − rCoG)≥3), d.o.f.: degrees of freedom for the test (Sect. 3.3.2), p0: probability of the SB profile at r = rin − rCoG to match that of the target’s continuum-component image (Lyα haloes are confirmed if p0 < 0.05), R. χ2: reduced χ2 of the SB fitting test, which is converted to a p0 value, R. χ2 (p0 = 0.05): reduced χ2 corresponding to the threshold 
, LAH: Whether the object has a Lyα halo or not. The SB profiles of RID = 23124 and 54891 were not tested due to the low S/N(rin − rCoG). We note that RID = 23135 has a negative S/N(rin − rCoG).
