prefiltered_detects

A dataframe of detections which has gone through the <code>prefilter()</code> function

datasets

Filtering of raw acoustic telemetry transmissions
from three acoustic telemetry companies (ATS, Lotek, Teknologic). The
filtering steps check for false positives caused by reflected transmissions
from surfaces and false pings from other noise generating equipment. The
filter is unique for each technology type. The package was written in
concert with the Interagency Telemetry Advisory Group (iTAG) and makes use
of the JSATS California Fish Tracking Database:
