  1. Columns give the number of contacts detected by motes by five duration categories and also the number of contacts that were not detected by the motes, but reported by a participant. Rows give the number of contacts reported by survey participants and also the number of contacts that were detected by the motes, but were not reported by the respective participant. Each percentage within a cell represents percentage of the row (right) and column totals (lower).
