* The labels correspond to the sub-panels (A-D) in figure 1. A is a circle source.
B is a linear source. C is a uniformly random filled circle. D is a uniformly
random filled circular shell.
Figure 1
Figure 1: This figure illustrates the geometries tested here, and the geometrical
parameters. The source distribution (green) has a scale length (radius or half length) of Ls.
The receiver distribution (red) has a scale length (radius) of Lx. The distance between the
source center and the receiver center is given by Δsx (blue). The tangent of the (Ls / Δsx)
provides an approximate measure of single-hemisphere azimuthal range of the sources
relative to the center of the array. The source geometries are referred to in the text as A)
circular, B) linear, C) randomly uniform, and D) randomly uniform shell.
