Descripción
Table presents the X-ray properties of all 1121 objects, including
fluxes in six selected energy bands, and public available optical data
for X-ray counterparts. X-ray flux in X/O flux ratio is the sum of
fluxes in (0.5-2keV) and (2-4.5keV) bands, while the optical flux
corresponds to R band. The represented hardness ratio was set using the
same X-ray bands. Photometric redshifts and K-corrections were measured
using the photometric information in five optical (Furusawa et al.,
2008, Cat. J/ApJS/176/1), three NIR (Hewett et al., 2006MNRAS.367..454H;
Hodgkin et al., 2009MNRAS.394..675H), and four MIR IRAC (SWIRE survey)
bands. Morphological classification was obtained using the galSVM code
(Huertas-Company et al., 2008A&A...478..971H,
2009A&A...497..743H), one of the new methods useful especially when
dealing with high-redshift sources and low-resolution data. With galSVM
we obtained the mean surface brightness, asymmetry, concentration index,
Gini, Smoothness, M20 moment of light, and two probabilities p1 and p2
that the galaxy belongs to early- (E, S0, S0/Sa) or late-type,
respectively. Stellarity and elongation parameters were obtained with
SExtractor. All objects with stellarity parameter greater or equal to
0.9 were considered as compact in this work. We included in our analysis
for early-type objects only those sources with p1 probabilities greater
or equal to 0.75, and for late-type objects all sources with
probabilities p2 greater than 0.5.
