Table 1.
Aperture scale radii permutations for TPB, 2 and TPB, 3.
| TPB, 2 permutations | TPB, 3 permutations |
|---|---|
| θ1θ4θ5|θ2θ3 | θ1θ2θ4|θ3θ5 |
| θ2θ4θ5|θ1θ3 | θ1θ3θ4|θ2θ5 |
| θ3θ4θ5|θ1θ2 | θ2θ3θ4|θ1θ5 |
Notes. The first permutation of each term corresponds to the explicit terms in Eq. (18). Interchanging the aperture radii left (right) of the vertical bars is an invariant property.
