  \caption{Fluctuations on the final map due to both the first $N_{\rm orbit}$~scans and the precession. The values are reported for the four cases described in Table~\ref{precDprTab}         treated in the text and for two different lifetimes. All the fluctuations are in arbitrary units considering  $\left|\Delta(Q+jU)_0\right|=1$ the maximum offset fluctuation in one orbit.}\label{dumpFMTab}
