Geometry around the Laue point La. Pl0 and Pl3 are planes whose distance from H0 and H3 is K. Plh is a plane normal to [{\bf n}_z] (downward surface normal). The Laue point La and point [P_1^{\prime\prime}] exist on Plh. Pli [(i \in \{ 1,2,4,5, \ldots, 17 \})] were not drawn for simplicity. [La_i^{\prime}] is a point whose distance from Hi [(i \in \{ 6,7, \ldots, 17 \})] is K. [P_{1}^{\prime}] is the initial point of the wavevector of the Bloch wave. [P_{1,k}^{\prime}] that appears in equation (14) in O et al. (2019) is the kth-numbered [P_{1}^{\prime}], i.e. the initial point of the wavevector of the kth-numbered Bloch wave where [k \in \{ 1, 2, 3, \ldots, 2n \}].
