Columns are as follows: (1) Sample; (2) Number of
sources used in the fit; (3) Best fit power-law
slope and 68\% confidence intervals; (4)~Log~$(N>S)-{\rm Log~}S$
normalization and 68\% confidence intervals.
Note that the normalization $K$ is not a parameter of the
fit but is determined by re-scaling the model to the 
number of objects in the sample.
The normalization $K$ reported here corresponds to the
surface densities at  $1\times 10^{-13}$~\ecs.
NOTE -- 
$^{a}$ As explained  in Sect.~3.1 we have excluded from the fit the 3 
BSS extragalactic sources having a flux greater than  
$1\times 10^{-12}$~\ecs.
