  1. We compare the average degree () network density (ρ), clique number (ω) and average clustering () of daily aggregated networks, for the contact network (c subscript), the co-presence network ( subscript), and the sampled co-presence networks (subscripts 1 to 3 according to the sampling method). Values are averaged over all the days of the study. In the case of SFHH, since on the second day there was activity only during the morning, only the values of the first day are reported. *The network is too large and too dense for the clique number to be determined in reasonable time via the usual algorithm.
