Table 1.

For the calculations of §§4 and 5, we determine T_uv using equations (2.1) and (2.2) with the distributions of and given in the first four rows, or by considering a maximally heterogeneous population for which 〈T〉 of the population infects all neighbours and 1−〈T〉 infects no neighbours. (The function δ is the Dirac delta function.)
