HOLZ Indexing

Figure 1 shows the HOLZ lines matching and indexing. The drawings of the lines make use of the kinematical theory of electron diffraction (with accelerating voltage correction). The controls of the right pane are distributed on seven different panes.

The arrows and reset tools are used to move the Laue Circle Center or to align the experimental and calculated patterns. The keyboard arrows do the same, with the translation speed selected by any combination of the Alt, Ctrl and Shift keys.
