2.2 DetectionsList objects
While Detections objects represent individual receivers, an array of receivers is stored as a list of detections objects: a DetectionsList.
detlst <- DetectionsList(det_1, det_2, det_3, det_4, det_5, det_6)
plot(detlst, main = "M\u00f6rrums\u00e5n array")
mtext("CRS: WGS 84, UTM zone 33N", adj = 0)
DetectionsList objects give handy summary tables when evaluated.
Below we can see the number of sync-tag emissions/detections within the array in addition to the detections of a tagged smolt swimming by (tag id: HR-53883 & PPM-53883).
