  1. Mean northings (\(\bar{x}\) North) and eastings (\(\bar{x}\) East) are distances of detections from known tag locations. The Euclidean distance (Euc Dist) is distance between locations calculated by the RAPT system and the actual tag location. The change in Euclidean distance (ΔEuc Dist) is the difference between the raw and kriged tag positions
