It is convenient for future reference to refine the basic categories of orthogonal and inclined scanning as follows:
The difference between monoclinic/orthogonal and monoclinic/inclined scanning is illustrated in Fig. 5.2.2.2. The orientation in the first case is fixed, while the second case applies to various orientations containing the monoclinic unique axis. The orientation can be defined by one free parameter, the angle ; we use instead Miller indices .
