Scientific Assumptions & Methodology

  • Applies to cubic lattices only.
  • Coordinates are represented in terms of fractional lattice vector lengths (0 to 1).
  • Negative indices are formatted using standard bar notation (e.g. 1̄).

Limitations & Educational Warnings

  • Symmetry-equivalent families of planes {hkl} or directions <uvw> are not expanded in v1.
  • HCP four-index Miller-Bravais indices (hkil) are deferred.
