The Chandra X-ray point source catalog in the DEEP2 Galaxy Redshift
  Survey fields
  We present the X-ray point-source catalog produced from the Chandra Advanced
CCD Imaging Spectrometer (ACIS-I) observations of the combined \sim3.2 deg2
DEEP2 (XDEEP2) survey fields, which consist of four ~0.7-1.1 deg2 fields. The
combined total exposures across all four XDEEP2 fields range from ~10ks-1.1Ms.
We detect X-ray point-sources in both the individual ACIS-I observations and
the overlapping regions in the merged (stacked) images. We find a total of 2976
unique X-ray sources within the survey area with an expected false-source
contamination of ~30 sources (~1%). We present the combined logN-logS
distribution of sources detected across the XDEEP2 survey fields and find good
agreement with the Extended Chandra Deep Field and Chandra-COSMOS fields to
f_{X,0.5-2keV}\sim2x10^{-16} erg/cm^2/s. Given the large survey area of XDEEP2,
we additionally place relatively strong constraints on the logN-logS
distribution at high fluxes (f_{X,0.5-2keV}\sim3x10^{-14} erg/cm^2/s), and find
a small systematic offset (a factor ~1.5) towards lower source numbers in this
regime, when compared to smaller area surveys. The number counts observed in
XDEEP2 are in close agreement with those predicted by X-ray background
synthesis models. Additionally, we present a Bayesian-style method for
associating the X-ray sources with optical photometric counterparts in the
DEEP2 catalog (complete to R_AB < 25.2) and find that 2126 (~71.4\pm2.8%) of
the 2976 X-ray sources presented here have a secure optical counterpart with a
<6% contamination fraction. We provide the DEEP2 optical source properties
(e.g., magnitude, redshift) as part of the X-ray-optical counterpart catalog.
