A histogram of the weights W _r,s for a BAO wavelet with radius ﹩{r}_{\mathrm{BAO}}=155\,{{\rm{h}}}_{75}^{-1}\,\mathrm{Mpc}﹩ and width ﹩{s}_{\mathrm{BAO}}=27\,{{\rm{h}}}_{75}^{-1}\,\mathrm{Mpc}﹩. The weights are normalized by the standard deviation across the full sample, and positive values correspond to grid locations that demonstrate an overabundance of galaxies distributed within a BAO-like shell. There is a clear excess of positive weights in the data (black) compared to the average and standard deviation of the no-BAO mocks (blue). The dotted line shows a Gaussian distribution—both the BAO and no-BAO mocks display a non-Gaussian tail of large overdensities. The largest positive weight corresponds to Ho’oleilana.
