We provide X-ray spectral fits and valid uncertainties for all the galaxies with counts ranging from 2 to 1325 (mean 76, median 19). We present here novel constraints that both X-ray luminosity L_X_ and X-ray spectral energy distribution bring to the galaxy evolutionary sequence HII->Seyfert/Transition Object->LINER->Passive suggested by optical data.2009ApJ...705.1336Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/705/1336CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 1999-)VII/260 : The SDSS-DR7 quasar catalog (Schneider+, 2010)II/294 : The SDSS Photometric Catalog, Release 7 (Adelman-McCarthy+, 2009)J/A+A/525/A127 : Properties of X-ray selected AGNs (Tasse+, 2011)J/ApJ/690/644 : Properties of SDSS QSOs in the ChaMP (Green+, 2009)J/AJ/135/10 : SDSS-DR4/RASS source matching (Parejko+, 2008)J/AJ/128/1002 : SDSS candidate type II quasars.
