Abstract:
We use publicly available XMM-Newton data to systematically compare
the hard X-ray photon indices, Γ2-10keV, and the iron Kα
emission lines of narrow- and broad-line Seyfert 1 (NLS1 and BLS1)
galaxies. We compile a flux-limited (f2-10keV≥1x10-12erg/s/cm2)
sample including 114 radio-quiet objects, with the 2-10keV luminosity
ranging from 1041 to 1045erg/s. 86 out of these 114 AGNs are
included in the CAIXA catalogue (Bianchi et al. 2009, Cat.
J/A+A/495/421). The redshift range of the present sample is z<0.37,
with only seven objects having z>0.2.

Note (1): Source type as follows:
NELG = Narrow-emission-line galaxy,
NLS1 = Narrow line Seyfert 1 galaxy,
BLS1 = Broad line Seyfert 1 galaxy.
NELGs are intermediate Seyfert galaxies whose broad line regions are
lightly obscured. We take NELGs with Γ>2.0 as NLS1s in our
analysis.
Note (2): The intrinsic width is fixed at 10eV for the EW measurements.
Note (3):
a = Object with the FWHMHβ calculated from the FWHMHα using the
relation FWHMHβ=1070*(FWHMHα/1000)1.03km/s given in
Greene & Ho (2005ApJ...630..122G 2005ApJ...630..122G). This object has the FWHMHα
measurement but lacks the FWHMHβ measurement. FWHMHα of
these objects are taken from Pietsch et al. (1998A&A...333...48P 1998A&A...333...48P),
Rodriguez-Ardila et al. (2000ApJS..126...63R 2000ApJS..126...63R) and Piconcelli et al.
(2006A&A...453..839P 2006A&A...453..839P), respectively.
Note (4): Calculated from the data available in Bianchi et al. (2009,
Cat. J/A+A/495/421).
