\caption{The expected number of events $\langle E_{\rm p} \rangle$ per
year in pixel lensing observations towards the M~31 galaxy for
different locations of sources and lenses is shown. We consider
the $100\times70$~arcmin$^2$ region oriented along the major axis of M~31.
and exclude events occurring within a radius of 8 arcmin of the
M~31 center. Sources and lenses in the M~31 bulge and disk are
indicated by indices 1 and 2, while lenses in the M~31 halo and MW
disk and halo by indices 3, 5 and 6. The first and second indices
refer to source and lens, respectively. The mean mass of bulge and
disk stars is $\sim$$0.31~M_{\odot}$ and $\sim$$ 0.53~M_{\odot}$,
respectively. For the lenses in the M~31 and MW halos we take a
mass of $\simeq$$ 0.5~M_{\odot}$ and a MACHO fraction $f_{\rm MACHO}
\simeq 20\%$. \label{table1}}
