Table S3.

The extent to which the number littoral forays by acoustically tagged lake trout during spring and summer were underestimated because of transmitter minimum ping frequency

		Underestimate of littoral forays, %
Data type	Minimum ping frequency, s	Spring	Summer
Intercept	0.00	0	0
Raw V16	17.00	12	22
Thinned	52.00	33	54
Thinned	87.00	50	74
Thinned	122.22	63	86

Differences were calculated using the slope estimate of the model in Fig. S1, and the percent underestimated was calculated using the estimated change in the number of forays at each minimum ping frequency relative to the intercept. For raw V16 data, only multiple detections were removed (i.e., successive detections with timestamp differences <17 s). For thinned data, all detections with timestamps less than 52 s, 87 s, or 122.22 s were removed. Underestimates for fall are not provided because minimum ping frequency did not influence the number of forays estimated during this season.
