\begin{table}%T3
\caption{This table lists the maximum detection significance reached during the
hexagonal dither observations (Sig$_{\rm rev,~max}$), the 
detection significance per season (Sig$_{\rm sX}$; where $X=1$,~2,~3 for the three seasons) 
and the detection significance for all observations together (Sig$_{\rm all}$), together 
with the corresponding fluxes ($F_{\rm s,~X}$) and errors in the fluxes for the 
IBIS/ISGRI 20$-$60~keV band. The ordering of sources is the same as used for Table~1.
When a source was not detected it is indicated with "$-$''; we then provide a 3$\sigma$ (statistical) upper limit
on the flux. Whenever Sig$_{\rm rev,~max}$
exceeds~7, the source long-term light curves are discussed in Sect.~\ref{light_curves}.
