We describe an XMM-Newton observation of the PKS0312-770 field,
which facilitates the spectral analysis of serendipitous sources previously
detected by CHANDRA. The combination of larger effective area and longer exposure
duration allows a significant increase in detected photons, and a lower limit in source
detection sensitivity. In particular the
hard X-ray normal galaxy unveiled by Fiore et al. (2000) is most likely
explained as a moderately absorbed (
cm-2) AGN.
We detect 52 sources (45 previously unreported) at a limiting flux of
~
ergs cm-2 s-1 in the 0.5-2 keV band. The Log N-Log S
curve is consistent with that derived from by XMM-Newton observations of the Lockman Hole field.
The flux determinations allow to check for any
inconsistency between the calibrations of the two observatories, which
is discussed.
