The zone axes can be displayed with or without the index label (depends onthe Display check box).Display (crystal indices)The status of the Display check box determines whether the zone axes displayed on the k-Space Controldisplay are labeled with their uvw index (check box checked) or shown without label.DiffractionDiffraction determines the maximum value used for the hkl indices of the diffraction spots displayed (anumber between 1 and 6). The diffraction-pattern spots can be displayed with or without the index label(depends on the Display check box).Display (diffraction)The status of the Display check box determines whether the spots of the diffraction pattern are shownwith or without label.Lattice pointsThe Lattice points value determines the number of lattice points used on the display (a number between1 and 6). For lower numbers fewer unit cells are shown. Only the central unit cell is indicated by lines.Kikuchi line indexThe Kikuchi line index determines up to what values of the hkl indices Kikuchi lines will be displayed.The acceptable maximum values will generally depend on the camera constant and whether the linesare shown with relative intensities or bright (see below). At low values, Kikuchi lines up to high indiceswill tend to fill the display completely and give a very messy result, while at high camera constants theuse of low maximum indices may result in the conspicuous absence of lines expected. In general, avalue of 3 is useful for lower camera constants. A value of 6 can be used if the Bright option is switchedoff.
