The three colored bands must be aligned on experimental Kikuchi bands and the band center positioned
on the Kikuchi pattern origin (i.e. transmitted beam position).
The accelerating voltage and camera length must be set first (before adjustment of the
pointing bands) (Fig. 3b). Adjust the error bars according to the measurements precision. When the indexing window is shown
for the first time, the default scale is either mm or nm-1 per pixel. The scale is adjusted using the
Scale pane (Fig. 4b).
The origin of the Kikuchi bands can be moved on the DP origin (transmitted beam position) using the green arrow
or any combination of Alt, Ctrl, Shift and the arrows keys.
The pointing bands are aligned using their small squares and crosses. They must be positionned to 3 intersecting
experimental pairs of Kikuchi lines. The red, green, blue bands on experimental Kikuchi pairs of lines of increasing
spacing.
Fine adjustment of the alignment of the bands with the Kikuchi lines is done using the red, green and blue dots.
Finally one can display the solutions in a diffraction dialogue.
Figure 13 One of the indexing solutions.
It may be necessary to increase the number of Laue zones, and decrease the Kikuchi threshold to make all
the bands appear on the drawing. A mouse click on the drawing will index the poles.
Note
The success of the indexing routine depends critically on the accelerating voltage, camera length, error bars settings and
adjustment of the bands on the narrowest bands. When no solution is found cross check them, align to new bands.
