cds-question@unistra.frx-ray-binary-starsgalaxiesastronomical-object-identificationsurveysThis study presents the final source catalog of the Chandra ACIS Survey of M33 (ChASeM33). With a total exposure time of 1.4Ms, ChASeM33 covers ~70% of the D_25_ isophote (R~4.0kpc) of M33 and provides the deepest, most complete, and detailed look at a spiral galaxy in X-rays. The source catalog includes 662 sources, reaches a limiting unabsorbed luminosity of ~2.4x10^34^erg/s in the 0.35-8.0keV energy band, and contains source positions, source net counts, fluxes and significances in several energy bands, and information on source variability. To constrain the nature of the detected X-ray source, hardness ratios were constructed and spectra were fit for 254 sources, follow-up MMT spectra of 116 sources were acquired, and cross-correlations with previous X-ray catalogs and other multi-wavelength data were generated. Based on this effort, 183 of the 662 ChASeM33 sources could be identified. Finally, the luminosity function (LF) for the detected point sources as well as the one for the X-ray binaries (XRBs) in M33 is presented. The resulting distribution is consistent with a dominant population of high-mass XRBs as would be expected for M33.2011ApJS..193...31Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/193/31CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 1999-)J/ApJS/187/495 : SNRs in M33 from optical and X-ray (Long+, 2010)J/ApJS/174/366 : Chandra ACIS survey of M33 (ChaSeM33) (Plucinsky+, 2008)J/A+A/448/1247 : XMM-Newton survey of M33 (Misanovic+, 2006)J/AJ/131/2478 : M31 and M33 UBVRI photometry (Massey+, 2006)J/ApJS/161/271 : The X-ray binary population in M33.
