The XMM-Large Scale Structure catalogue: X-ray sources and associated optical data. Version I

M Pierre, L Chiappetti, F Pacaud…�- Monthly Notices of�…, 2007 - academic.oup.com
Following the presentation of the XMM-Large Scale Structure (XMM-LSS) survey X-ray
source detection package by Pacaud et al., we provide the source lists for the first surveyed
5.5 deg2. The catalogues pertain to the [0.5–2] and [2–10] keV bands and contain in total
3385 point-like or extended sources above a detection likelihood of 15 in either band. The
agreement with deep log N–log S is excellent. The main parameters considered are
position, count rate, source extent with associated likelihood values. A set of additional�…

The XMM-LSS survey: the Class 1 cluster sample over the initial 5 deg2 and its cosmological modelling

F Pacaud, M Pierre, C Adami, B Altieri…�- Monthly Notices of�…, 2007 - academic.oup.com
We present a sample of 29 galaxy clusters from the XMM-LSS survey over an area of some
5 deg2 out to a redshift of z= 1.05. The sample clusters, which represent about half of the X-
ray clusters identified in the region, follow well-defined X-ray selection criteria and are all
spectroscopically confirmed. For all clusters, we provide X-ray luminosities and
temperatures as well as masses, obtained from dedicated spatial and spectral fitting. The
cluster distribution peaks around z= 0.3 and T= 1.5 keV, half of the objects being groups with�…
