SB profiles from the optimized NBs with results of the Lyα halo tests. The gray, black, and blue points indicate the observed radial profiles, those used for the fit (with binning if needed), and the best-fit SB profiles of the PSF-convolved continuum-like component, respectively. The x error bars of the black points mark the range for each (combined) radial bin. The cyan shaded areas represent the radial ranges, r = r_in − r_CoG (see Sect. 3.3). The classification of LAH or non-LAH, the S/N of the flux at r = r_in − r_CoG, and the probability of the null hypothesis that the SB profile at r = r_in − r_CoG matches that of the target’s continuum-component profile are shown at the top of each panel.
