Track of salmon 34435, tagged with a V7 transmitter (rbi 40–80 s). The time series (a) show the X- and Y-coordinates of the VPS track (blue) and YAPS track (green). The other panels show the track in 2D from 13:00 on, resulting from the different methods: VPS (b), HPE filter (c), good performance filter (d), bad performance filter (e) and YAPS (f). The gray polygon marks the contour of the receiver array
