Previous Results
A. Coil et al. 2009 projected cross-correlation function (wp) in AEGIS of 132 X-ray AGNs with 4669 galaxies from DEEP2 survey.
Limitations
Deep2 is a unique catalogue of spectroscopic redshifts.
Small number of X-ray AGN in AEGIS/DEEP2.
Other studies are not possible, like the study of the Luminosity dependent evolution of the AGN clustering.
Limitations

Probability Density Function (PDF) of Photometric Redshifts
Binned distribution with dz=0.04 from z=0 up to z=6
Our redshift bin is ±300 h -1Mpc = 5 bins in the PDF
Samples
110 X-ray detected AGN galaxies in AEGIS/CFHTLS
~21000 PDFs ~106 random galaxies
