Abstract:
In 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°2 down to a flux
limit of 3x10-16ergs/s/cm2, which corresponds to a luminosity of
2x1034ergs/s at a distance of 840kpc.

Note (1): The nucleus; because of pileup, counts and flux are not true values.
Note (2): Most probable value, for details see Sec. 2.
Note (3): For sources with more than 100 counts, luminosity was computed from
spectral fit, otherwise Γ=2 and NH=6e+20cm-2 are assumed.

History:
* 26-Jun-2006: From electronic version of the journal
* 24-Dec-2006: Several CXOU numbers were corrected in table4 and table5
(differed be a few arcsec from the CXOU number in table1)
* 31-May-2007: the designations originally called "CXO" were corrected to
CXOU according to the Chandra conventions.
