The Thales project uses data from a number of high-profile multiwavelength survey fields such as the Cosmological Evolution Survey (COSMOS), the All-wavelength Extended Groth strip International Survey (AEGIS), the Chandra Deep Field South (CDFS), the Chandra Deep Field North, the XMM-XXL survey and the XMM/SDSS serendipitous survey. Part of these data, including X-ray source catalogues, various X-ray data products, identifications of X-ray sources with optical counterparts, photometric redshift estimates, compilations of spectroscopic redshifts etc, are available at the following link .

Also relevant to the Thales project objectives is the X-ray Background Calculator hosted by the National Observatory of Athens and based on methods described in the Akylas et al. (2012).
