The XMM Cluster Survey: X-ray analysis methodology

Lloyd-Davies, E. J., Romer, A. Kathy, Mehrtens, Nicola et al.

Understand

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 describe the data processing methodology applied to the 5,776 XMM observations used to construct the current XCS source catalogue.
  • A total of 3,675 > 4-sigma cluster candidates with > 50 background-subtracted X-ray counts are extracted from a total non-overlapping area suitable for cluster searching of 410 deg^2.
