Comparison of properties for the contact networks obtained from sensors and diaries.

On the day of collection of the contact diaries, only 295 students out of the 327 participating correctly wore their sensors. All network properties for the contact diaries network are computed on its symmetrized version. In this summary table we assume that if a contact is reported by at least one of the two nodes, it exists. The right side of the table is performed after matching the two networks. Matching is done by removing the nodes who did not participate to the survey and the ones who did not have contacts recorded by sensors on the 4th day of the study. A * close to the SPL average means that after the match some isolated nodes appeared. In this case, we computed the average on the connected pairs only. Standard deviations are given in parentheses.
