\begin{table}%T6
\caption{Mean ($\overline{F}$) observed fluxes in the 20$-$60~keV (denoted by A) 
and 60$-$150~keV (denoted by B) bands, respectively, over the whole AO-3 monitoring program.
The error given for $\overline{F}$ is the error in the mean. 
"$\sigma$'' denotes the standard deviation of the averaged values and gives a measure of the 
variability of a source.
The ordering of sources is the same as used for Table~1.}
