basic reproductive number, R0, as a function of the field size for modified power law 2 dispersal kernel.

The file represents the basic reproductive number, R0, as a function of the field size for exponential dispersal kernel. 1st column distance [m]; 2nd column R0. Spatial grid 120x120 gridpoints (d from 0 m to 100 m) 150x150 gridpoints (d from 110 m to 250 m). Plotted as dashed curve in Fig. 1. The data was generated by numerical solution of Eq. (6) in the manuscript
