  In this Paper we present the source catalog obtained from a 942 ks exposure
of the Chandra Deep Field South (CDFS), using ACIS-I on the Chandra X-ray
Observatory. Catalog generation proceeded simultaneously using two different
methods; a method of our own design using a modified version of the SExtractor
algorithm, and a wavelet transform technique developed specifically for Chandra
observations. The detection threshold has been set in order to have less than
10 spurious sources, as assessed by extensive simulations. We subdivided the
catalog into four sections. The primary list consists of objects common to the
two detection methods. Two secondary lists contain sources which were detected
by: 1) the SExtractor algorithm alone and 2) the wavelet technique alone. The
fourth list consists of possible diffuse or extended sources. The flux limits
at the aimpoint for the soft (0.5--2 keV) and hard (2--10 keV) bands are
5.5E-17 erg/s/cm^2 and 4.5E-16 erg/s/cm^2 respectively. The total number of
sources is 346; out of them, 307 were detected in the 0.5--2 keV band, and 251
in the 2--10 keV band.
  We also present optical identifications for the catalogued sources. Our
primary optical data is R band imaging to a depth of R~26.5 (Vega). We found
that the R-band/Chandra offsets are small, ~1 arcsec. Coordinate
cross-correlation finds 85% of the Chandra sources covered in R to have
counterparts within the 3-sigma error box (>~1.5 arcsec depending on off-axis
angle and signal-to-noise). The unidentified fraction of sources, approximately
~10--15 %, is close to the limit expected from the observed X-ray flux to
R-band ratio distribution for the identified sample.
