Copycat dynamics in leaderless animal group navigation

Table 1 Simulation model parameter descriptions and values

Model parameter	Description	Fixed value	Range of values
N	Total group size (individuals)	40	2, 5, 10, 15, 20, 25, 30, 40, 50, 60, 80, 100
R _C	Radius of collision avoidance	2	-
R _O	Radius of orientation	15	-
ξ	Standard deviation of added environmental noise/error	0.1	-
w	Weighting towards individual navigation (tactic factor)	-	0.01, 0.02, 0.04, 0.06, 0.08, 0.1, 0.12, 0.15, 0.2, 0.25, 0.3, 0.4, 0.5, 0.7, 1
k	Number of influential nearest neighbours	-	1, 2, 3, 4, 5, 7, 9, 12, 15
ϵ	Standard deviation of individual navigation error	-	0, 0.2, 0.5, 1, 1.5, 2, 3, 5

Parameters have either no units or arbitrary distance units.
Fixed parameters are the same throughout all simulations. Parameters that have a range of values are explored in simulations using each combination of values in turn.
