Abstract:
Wide area X-ray and far infrared surveys are a fundamental tool to
investigate the link between AGN growth and star formation, especially
in the low-redshift universe (z<1). The Herschel Terahertz Large Area
survey (H-ATLAS) has covered 550deg2 in five far-infrared and sub-mm
bands, 16deg2 of which have been presented in the Science
Demonstration Phase (SDP) catalogue. Here we introduce the XMM-Newton
observations in H-ATLAS SDP area, covering 7.1deg2 with flux limits
of 2*10-15, 6*10-15, and 9*10-15erg/s/cm2 in the 0.5-2, 0.5-8
and 2-8keV bands, respectively.
We present the source detection and the catalogue, which includes
1700, 1582 and 814 sources detected by emldetect in the 0.5-8, 0.5-2
and 2-8keV bands, respectively; the number of unique sources is 1816.
We extract spectra and derive fluxes from power-law fits for 398
sources with more than 40 counts in the 0.5-8keV band. We compare the
best-fit fluxes with the catalogue ones, obtained by assuming a common
photon index of Gamma=1.7; we find no bulk difference between the
fluxes, and a moderate dispersion of s=0.33dex. Using wherever
possible the fluxes from the spectral fits, we derive the 2-10keV Log
N-Log S, which is consistent with a Euclidean distribution. Finally,
we release computer code for the tools developed for this project.
Description:
X-ray sources were detected in the 7.1deg2 XMM-Newton observations
of the H-ATLAS field. Source detection was done in two steps, first
using the ewavelet software, and then using emldetect. Sources
detected by both programs are presented in the main tables, while
sources only detected by PWXDetect are presented in the supplementary
tables. The same columns are present in both the main and
supplementary tables, but those coming from emldetect are empty in the
supplementary table.

Note (1): The RAdeg and DEdeg columns are registered to the reference frame of
the SDSS-DR7 QSOs (Schneider et al. 2010AJ....139.2360S 2010AJ....139.2360S). All other
coordinate columns are not registered and may present a minimal, residual
shift.
Note (2): The error on position was obtained by dividing the EMLDetect
RADEC_ERR by sqrt(2). The RADEC_ERR from EMLDetect is computed as
sqrt(RAERR2+DEC_ERR2). However, when two normalised one-dimensional
gaussians of σ are combined, the corresponding normalised
bi-dimensional gaussian also has σ, not sqrt(2)*σ, which is
what one would get with the expression above. Therefore, we divided
the EMLDetect value by sqrt(2).
Note (3): σ of Gaussian model in pixels (1pix=4arcsec)
