Abstract:
Since its launch in 1999, the XMM-Newton mission has compiled the
largest catalogue of serendipitous X-ray sources, with the
3XMM being the third version of this catalogue. This is because of the
combination of a large effective area (5000cm2 at 1keV) and a wide
field of view (30 arcmin). The 3XMM-DR6 catalogue contains about
470000 unique X-ray sources over an area of 982deg2. A significant
fraction of these (100178 sources) have reliable optical, near/mid-IR
counterparts in the SDSS, PANSTARRS, VIDEO, UKIDSS and WISE surveys.
In a previous paper we have presented photometric redshifts for these
sources using the TPZ machine learning algorithm. About one fourth of
these (22677) have adequate photon statistics so that a reliable
X-ray spectrum can be extracted. Obviously, owing to both the X-ray
counts selection and the optical counterpart constraint, the sample
above is biased towards the bright sources. Here, we present
XMMFITCAT-Z: a spectral fit catalogue for these sources using the
Bayesian X-ray Analysis (BXA) technique. As a science demonstration of
the potential of the present catalogue, we comment on the optical and
mid-IR colours of the 765 X-ray absorbed sources with
NH>1022cm-2. We show that a considerable fraction of X-ray
selected AGN would not be classified as AGN following the mid-IR
W1-W2 vs. W2 selection criterion. These are AGN with lower
luminosities, where the contribution of the host galaxy to the MIR
emission is non-negligible. Only one third of obscured AGN in X-rays
present red colours or r-W2>6. Then it appears that the r-W2
criterion, often used in the literature for the selection of obscured
AGN, produces very different X-ray absorbed AGN samples compared to the
standard X-ray selection criteria.
Description:
The XMM-Newton spectral-fit Z catalogue (XMMFITCAT-Z) contains
spectral- fitting results for 30816 detections, corresponding to
22,677 unique sources. This catalogue is produced by applying
automated spectral fits to the EPIC spectral data contained within the
XMM-Newton serendipitous source catalogue and using the distance
information contained in XMMPZCAT. The version of the catalogue used
to construct the current XMMFITCAT is 3XMM-DR6.
3XMM-DR6 is the third generation catalogue of serendipitous X-ray
sources from the European Space Agency (ESA) XMM-Newton observatory,
and has been created by the XMM-Newton Survey Science Centre (SSC) on
behalf of ESA. The 3XMM-DR6 catalogue contains photometric information
for 678,680 source detections, corresponding to 468,440 unique
sources. As part of the catalogue production, spectra and time series
are extracted in the case of detections with more than 100 counts
collected in the EPIC camera. This corresponds to 149998 detections,
and 102,157 unique sources.
XMMPZCAT contains 100178 3XMM sources outside the Galactic plane
(|b|>20deg) with highly reliable optical counterparts in the
SDSS-DR13 or Pan-STARRS-DR1 catalogues. It offers photo-z for about
50% of the X-ray sources within the XMM-Newton observations selected
for building the catalogue.
The XMM-Newton spectral-fit database is constructed by using spectral
data from the 3XMM-DR6 catalogue, but not all detections with
extracted spectra are included in this database. To ensure the
reliability of the spectral- fitting results, a constrain has been
imposed to the number of counts collected in the X-ray spectra and as
result, some detections are rejected in the automated spectral-fit
pipeline. Moreover, only detections with redshifts in XMMPZCAT have
been included.
Here we also provide the sample of 977 X-ray absorbed AGN identified
from the XMMFITCAT-Z catalogue, as presented in the paper.

Global notes:
Note (G1): Corrected source coordinates and, in the case of multiple detections,
they correspond to the weighted mean of the coordinates for the
individual detections.
Note (G2): Leiden/Argentine/Bonn (LAB) Survey of Galactic HI
[Kalberla et al., 2005A&A...440..775K 2005A&A...440..775K, Cat. VIII/76]
Note (G3): Computed by adding all available instruments and exposures for the
corresponding observation
Note (G4): This column contains the remaining models with relative evidence,
with respect to P_MODEL, lower than 30, i.e. 'very strong evidence'
accordingly to the scale of Jeffreys 1961. Assuming all models are a
priori equally probable, there is no statistical reason to rule out
any of the models in the set formed by P_MODEL and A_MODELS
Note (G5): Models are:
wapo = absorbed power law
wamekal = absorbed thermal
wamekalpo = absorbed thermal plus power law
wapopo = absorbed double power law
Note (G6): Null if spectroscopic redshift is available
Note (G7): For the wapopo model, the spectral parameters corresponds to the
inner component.
