Measurement splitting and contact aggregation process. The figure shows the measurements collected in the first 20 min of August 8th, 2020, between node 26 and 27 at the am-pri camp. The measurements (light colors) are colored according to the division into contact characterized by \(\tau _{\mathrm{time}} =90\) s and \(\tau _{\mathrm{space}} =2\) m. Each contact is depicted as a horizontal bar from its beginning to its end, where the height of the bar represents the median distance
