I compared the receivers found in dwc:eventRemarks with the receivers in the original detections.csv. The following receivers and associated locations should not be present in the data:
"receiverIDfromEventRemarks","locationID","locality","(Number of Rows)"
"VR2W-119078","V2LNR085","(NA)",1
This affects 2 rows. I will remove it from the data, but it should be investigated why they are present.
