Figure 4
When integrating the n-beam T-T equation (performing the T-T simulation for n = 8), the crystal was divided into small octagonal pyramids. l₁ was calculated to be 29.493 µm. D_i^(l)(R⁽¹⁾) can be calculated from D_j^(m)(R_k⁽⁰⁾) ( $[i, j, k \in \{ 0, 1, 2, \ldots, 7 \},]$ l, m ∈ {0, 1}) by solving equation (1)
