Projected correlation function in proper coordinates in the J0053+1234 region in three redshift bins. The correlation function is estimated as described in the text. The solid curve shows a correlation function of the form of eq. (4) with ﹩r_{0}=3.5\,\mathrm{Mpc}\,﹩ and ﹩\gamma =1.8﹩, projected through ﹩\Delta v_{r}=1000\,\mathrm{km}\,\,\mathrm{s}\,^{-1}﹩ at ﹩z=0.55﹩ according to eq. (2).
