Fig. 3: Policies based on distance and duration.
From: Digital proximity tracing on empirical contact networks for pandemic control
(a): The signal strength threshold Tp and the duration threshold Td defining the policies are reported. Contacts with a duration larger than Td and signal strength larger than Tp are considered at risk. The last column gives the fraction of the total number of interactions of the CNS data set that they correspond to. A larger value of the magnitude of the signal strength tends to correspond to a larger distance, such that in the second column the thresholds go from the least to the most restrictive policy. The policies are sketched in (b).
