Track of eel 100, tagged with a V13 transmitter (rbi 17–33 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 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
