\tablefoot {The average sensitivity per $30^\prime$ pixel or per {\it FWHM}$^2$ resolution element ($\delta T$ and $\delta T/T$, respectively) is given in CMB~temperature units (i.e.~equivalent thermodynamic temperature) for 14~months of integration. The white noise (per frequency channel and 1~s of integration) is given in antenna temperature units. See~Tables~\ref{table:opt1} and~\ref{table:meas_sens} for LFI measured performance.}
