Left-hand panel: projected correlation function for the whole spectroscopic sample (761 sources). Error bars are obtained as jack-knife resampling of the data set under consideration. The dashed line represents the best fit to the data corresponding to γ= 1.6 and r₀ = 6.7 Mpc, while open squares illustrate the results obtained by Hawkins et al. (2003) for the entire population of 2dFGRS galaxies. Right-hand panel: projected correlation function for the subsample of radio-AGNs (536 sources). Error bars are obtained as for the spectroscopic sample. The dashed line represents the best fit to the data corresponding to γ= 2.0 and r₀ = 10.9 Mpc, while open squares illustrate the results obtained by Madgwick et al. (2003) for the population of early-type 2dFGRS galaxies.
