spectrum analysis made by @outram using the final version of the 2QZ catalog, containing 22,652 QSOs.

The AERQS AGN catalog samples a part of the QSO luminosity function which is fainter than that sampled by the 2QZ. The mean absolute magnitudes of the total AERQS QSOs are $M_B=-23.49$ and -22.99 for the EdS and $\Lambda$CDM, respectively. The 2QZ QSOs at $0.3\le z\le 2.2$ are brighter than local AGN, with $M_J=-24.43$ and -25.11 for EdS and $\Lambda$, respectively. In our comparison, we do not take into account the dependence of the TPCF on the absolute magnitude of the sample, since the QSO population exhibits a strong luminosity evolution with redshift and @ximb have demonstrated that the dependence of the clustering on $M_B$ is very weak. A correction of the luminosity dependence of the TPCF would increase the AERQS value, enhancing the redshift evolution of the clustering.

Modeling the redshift evolution of QSO clustering
=================================================

By adding the AERQS value of local QSO correlation length to the 2QZ estimates at higher redshifts, we have now the complete picture of the QSO clustering properties up to $z\sim 2.5$, as summarized in Fig. \[conserving\]. In the following, we introduce a model which can be
