an all-sky survey, using only clusters with $M \ge 5$~$\times$ $10^{14}~M_\odot~h^{-1}$ to compute the optical depths (see Fig.~\ref{fig:arcCounts_mass}).}

$^{(1)}$~Surface brightness limit used to determine the number of arcs;
$^{(2)}$~arc length-to-width ratio thresholds;
$^{(3)}$~redshift distribution and number count function, as introduced in Figs.~\ref{fig:zd} and~\ref{fig:cc}. \\
Values with and without brackets correspond to $S_{850~\mu{\rm m}} / S_{1.4~{\rm GHz}}=100$ and~$50$, respectively.
