Prior models for coupling coefficients and optode positions. U(a, b) denotes the uniform density between [a, b]. The perturbation δθ in the location is given in degrees. The width of one source or detector fiber corresponds to 2.3° and the separation of adjacent optodes in the equiangular case ζ 0 is 11.25°. (1° is equivalent to 0.44mm along the domain boundary ∂Ω)
| Coupling coefficients | Optode angular locations | ||
|---|---|---|---|
| (1) | si, dj ∼ U(0.9, 1) | δi, ηj ∼ U(0, π/360) | δθ ∼ U (−2°, +2°) |
| (2) | U(0.7, 1) | U(0, π/180) | U (−4°, +4°) |
| (3) | U(0.5, 1) | U(0, π/90) | U (−8°, +8°) |
| (4) | U(0.2, 1) | U(0, 3π/45) | U (−12°, +12°) |
