Sky coverage in the soft band (0.5-2 keV) for the 940ksec exposure
of the CDFS.  The flux in cgs units is obtained multiplying column 1
by the conversion factor, which is (4.6+- 0.1) X 10^{-12} (Rosati et
al. 2001).  

Column 1 Net count rates in the soft band (0.5-2 keV).
Column 2 Sky coverage in square degree
