\tablefoot {\tablefoottext{a}{The selection of the alignment cases is described in Sect.~6.1.} \\
\tablefoottext{b}{Based on an electromagnetic  model of the as-built geometry, whose RF properties have been correlated against measurements, and which has been corrected for cool-down effects (Sandri et~al. \cite{LFIOptics}).} \\
\tablefoottext{c}{Based on an electromagnetic model of the as-built geometry (Maffei et~al. \cite{HFIOptics}); cool down effects have a negligible impact.} \\
\tablefoottext{d}{A set of small-scale spatial deformations was synthesized similar to those measured on the SR by interferometry.} \\
\tablefoottext{e}{In some cases the feedhorn patterns were significantly different from the predicted ones; for these cases a hybrid pattern was developed which accounted for the   measurements (Maffei et~al. \cite{HFIOptics}).}}
