Table 2. The transformations of the reciprocal-lattice basis vectors of a cubic lattice (a = 4 Å) to pre-selected zones.

The last column shows the corresponding two-dimensional lattice parameters.

Zone axis	[S*]	, ,
[110]		0.25 Å−1, 0.36 Å−1, 90°
[111]		0.35 Å−1, 0.35 Å−1, 60°
[123]		0.56 Å−1, 0.61 Å−1, 137°
[431]		1.03 Å−1, 0.79 Å−1, 23°
