  1. The first community is represented as a circle with radius 0.15, and the second community is represented as circle "B" with radii 0.15, 0.134, and 0.116, respectively. The offset is the distance between the centers of the two circles. The number of simulations is 1000, and the type 1 error rate is set at 0.05.
