\caption{In flight detectors performance: we report the
noise equivalent temperature at 1 Hz, derived from the noise
equivalent voltage measured in flight as in Sect.~\ref{subs:flightnoise}, from the responsivity estimated as in Sect.~\ref{subs:pixpixcal} and from the spectral calibrations of Sect.~\ref{subs:fts}. In our survey, this frequency corresponds to
multipoles $400 \protect \la \ell \protect\la 1200$. The noise increases at
lower and at higher frequencies, as shown in Fig.~\ref{fig:nep}.\label{tab:nep}}
