cds-question@unistra.frx-ray-sourcesspectroscopyWe examine the X-ray spectra and variability of the sample of X-ray sources with L_X_~10^31^-10^33^ergs/s identified within the inner 9' of the Galaxy by Muno et al. Very few of the sources exhibit intraday or intermonth variations.2004ApJ...613.1179Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/613/1179CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 2002-)J/ApJ/589/225 : Chandra X-ray sources toward Galactic Center (Feigelson+ 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/613/1179https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/613/1179http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/613/1179https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/613/1179https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/613/1179http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/613/1179GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/613/1179/table2 (Spectra of Individual Point Sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/613/1179/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/613/1179/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/613/1179/table2?GETtext/xml+votable180.050000true266.241667-29.0861110.005555555555555556Cone search capability for table J/ApJ/613/1179/table7 (Sources with long-term variability)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/613/1179/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/613/1179/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/613/1179/table7?GETtext/xml+votable180.050000true266.26625-29.0141670.005555555555555556Cone search capability for table J/ApJ/613/1179/table6 (Sources with short-term variability)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/613/1179/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/613/1179/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/613/1179/table6?GETtext/xml+votable180.050000true266.3225-29.1138890.005555555555555556Chandra6/28827 28830https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/613/1179?format=asciiX-rayOpticaldefaultJ/ApJ/613/1179/table2Spectra of Individual Point SourcesCXOGCIAU Designationcharprimaryd_Pchi2Degrees of freedom for Pchi2intrecnoRecord number assigned by the VizieR team.
