  1. The table summarizes the contingency data used to estimate contact success rate, false-negative rate and contact-triggered GPS location success rate. ‘Tot. events’, ‘True pos.’, ‘False neg.’ and ‘False pos.’ denote, respectively, the total events, true positives, false negatives and false positives used to estimate the rates. 1L-P3 = trials with one logger set at power 3; 1L-P7 = trials with one logger set at power 7; 2L-P3 = trials with two loggers set at power 3; 2L-P7 = trials with two loggers set at power 7; 3L-P3 = trials with three loggers set at power 3; 3L-P7 = trials with three logger set at power 7
