Abstract:
    The ROSAT Deep Survey in the Lockman Hole is the most sensitive X-ray
    survey performed to date, encompassing an exposure time of 207ksec
    with the PSPC and a total of 1.32Msec with the HRI aboard ROSAT. Here
    we present the complete catalogue of 50 X-ray sources with PSPC fluxes
    (0.5-2 keV) above 5.5x10-15erg/cm2/s.

Note (1): Dominant weight to the X-ray position comes from PSPC (P) pointing,
          HRI (H) pointing or HRI (R) raster scan.
Note (2): Bands:
     H: hard band, 0.5-2.0KeV
     S: soft band, 0.1-0.4keV
    H1: split hard band, 0.5-0.9keV
    H2: split hard band, 0.9-2.0keV
