Abstract:
The XMM Cluster Survey (XCS) is a serendipitous search for galaxy
clusters using all publicly available data in the XMM-Newton Science
Archive. Its main aims are to measure cosmological parameters and
trace the evolution of X-ray scaling relations. In this paper we
present the first data release from the XMM Cluster Survey (XCS-DR1).
This consists of 503 optically confirmed, serendipitously detected,
X-ray clusters. Of these clusters, 256 are new to the literature and
357 are new X-ray discoveries. We present 463 clusters with a redshift
estimate (0.06<z<1.46), including 261 clusters with spectroscopic
redshifts. The remainder have photometric redshifts. In addition, we
have measured X-ray temperatures (TX) for 401 clusters
(0.4<TX<14.7keV).

Note (1): the XCS-Zoo project, described in section 4.1, classifies the
cluster candidates from a visual inspection of optical images.
The result classes are g(gold), s(silver), b(bronze) candidate clusters;
and the optical image used for the best zoo classification is one of
DR7 (SDSS-DR7 images), S82 (SDSS-Stripe 82), NXS (NOAO-XMM Cluster Survey,
see section 2.1), or DSS (Digital Sky Survey).
