The 3XMM/SDSS Stripe 82 Galaxy Cluster Survey II. X-ray and optical
  properties of the cluster sample
  We present X-ray and optical properties of the optically confirmed galaxy
cluster sample from the 3XMM/SDSS Stripe 82 cluster survey. The sample includes
54 galaxy clusters in the redshift range of 0.05-1.2, with a median redshift of
0.36. We first present the X-ray temperature and luminosity measurements that
are used to investigate the X-ray luminosity-temperature relation. The slope
and intercept of the relation are consistent with those published in the
literature. Then, we investigate the optical properties of the cluster galaxies
including their morphological analysis and the galaxy luminosity functions. The
morphological content of cluster galaxies is investigated as a function of
cluster mass and distance from the cluster center. No strong variation of the
fraction of early and late type galaxies with cluster mass is observed. The
fraction of early type galaxies as a function of cluster radius varies as
expected. The individual galaxy luminosity functions (GLFs) of red sequence
galaxies were studied in the five ugriz bands for 48 clusters. The GLFs were
then stacked in three mass bins and two redshift bins. Twenty clusters of the
present sample are studied for the first time in X-rays, and all are studied
for the first time in the optical range. Altogether, our sample appears to have
X-ray and optical properties typical of average cluster properties.
