Table 1.

Probability of possible outcomes in a game theory model where a farmer and his/her neighbour are deciding whether to use prophylaxis for sheep scab.

Probability	Dip		Inject
	Upland	Lowland	Upland	Lowland
Pr(scab | treatment)	0.092	0.036	0.099	0.041
Pr(no scab | treatment)	0.908	0.964	0.901	0.959
Pr(scab | no treatment)	0.139	0.052	0.139	0.052
Pr(no scab | no treatment)	0.861	0.948	0.861	0.948
Pr(infection | neighbour infected)	0.91	0.2	0.91	0.2
Pr(healthy | neighbour infected)	0.09	0.8	0.09	0.8

These values were estimated using data from the literature (see supplementary material) and were used along with Fig. 1 in order to estimate the values of the probability parameters in the model.
