cds-question@unistra.frx-ray-sourcesx-ray-binary-starsgalaxiesIn this paper we present the source list for three Chandra observations of the Local Group galaxy M33. The observations are centered on the nucleus and on the star-forming region NGC 604. We detect a total of 261 sources in an area of 0.2{deg}^2^ down to a flux limit of 3x10^-16^ergs/s/cm^2^, which corresponds to a luminosity of 2x10^34^ergs/s at a distance of 840kpc.2005ApJS..161..271Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/161/271CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/89/85 : Blue and red supergiants in M33 (Ivanov+ 1993)J/AJ/110/2715 : UBV photometry in NGC 6822, M31 and M33 (Massey+ 1995)J/ApJ/469/629 : UV-brightest stars of M33 and its nucleus (Massey+ 1996)J/AJ/105/499 : OB Associations and Spiral Structure in M33 (Regan+ 1993)J/ApJ/501/153 : VRB photometry in NGC 6822, M31 and M33 (Massey 1998)J/A+A/373/438 : X-ray view of M33 after ROSAT (Haberl+, 2001)J/A+A/426/11 : XMM-Newton survey of M33 (Pietsch+, 2004)J/ApJS/150/19 : ChaMP.
