    dct:description "This table comprises CAIXA, the &quot;Catalog of AGN In the XMM-Newton Archive&quot;. It consists of all the radio-quiet, X-ray unobscured (N&lt;sub&gt;H&lt;/sub&gt; &lt; 2 x 10&lt;sup&gt;22&lt;/sup&gt; cm&lt;sup&gt;-2&lt;/sup&gt;) active galactic nuclei (AGN) observed by XMM-Newton in targeted observations, whose data were public as of March 2007. With its 156 sources, this is the largest catalog of high signal-to-noise X-ray spectra of AGN. All the EPIC pn spectra of the sources in CAIXA were extracted homogeneously, and a baseline model was applied in order to derive their basic X-ray properties. These data are complemented by multiwavelength data found in the literature: black hole masses, full width half maximum (FWHM) of H(beta), radio and optical fluxes. In their paper, the authors describe their homogeneous spectral analysis of the X-ray data in CAIXA and present all the results for the parameters adopted in their best-fit models. This table was created by the HEASARC in March 2009 based on the &lt;a href=\"https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/495/421\"&gt;CDS catalog J/A+A/495/421&lt;/a&gt; files table1.dat, table2.dat and table3.dat.
