Abstract:
    From August 23 through September 24, 2003, the INTEGRAL Observatory
    conducted a deep survey of Galactic-Center region with a
    record-breaking sensitivity at energies above 20keV. We detected a
    total of 60 sources with fluxes above 1.5mCrab in the range 18-60keV.

Note (1): b: Source lies at a distance of 0.7deg from the galactic center
      and may be a superposition of several weaker point like sources.
Note (2): In the energy band 18-60keV, 1mCrab = 1.3612*10-11erg/s/cm2.

Note (3): Only the statistical flux uncertainties are given. The systematic
           uncertainty in absolute flux value (∼10%) is not included.
Note (4): Classification uses the following abbreviations:
    LMXB: low mass X-ray binary
    HMXB: high mass X-ray binary
      BH: black hole
      NS: neutron star
     AGN: active galactic nucleus
      CV: cataclysmic variable
     AXP: anomalous X-ray pulsar
     SGR: soft gamma repeater
