Bundled data: crystod/CIR_data.txt.gz contains the ISO-IR tables of the
ISOTROPY Software Suite (H. T. Stokes, B. J. Campbell and R. Cordes,
"Tabulated irreducible representations of the crystallographic space
groups", Acta Cryst. A69, 388-395 (2013); iso.byu.edu/irtables.php).
Please cite that work when the irreducible-representation tables are used
in published research.

Bundled examples: crystod/examples/ holds example inputs and the README files
that describe them (the files behind the --example options, and copies of
selected directories of the repository's example/, which crystod-example
copies out). They are covered by the MIT License above, like the code, with
these exceptions:

- crystod/examples/23_symmetry_mode/POSCAR_KGeCl3_Cm,
  POSCAR_KGeCl3_P4mmm_pseudo, POSCAR_SeO2_Cmme_pseudo and POSCAR_SeO2_Pmc21
  are structures from the Materials Project (mp-998231 KGeCl3, mp-560882
  SeO2; A. Jain et al., "Commentary: The Materials Project: A materials
  genome approach to accelerating materials innovation", APL Mater. 1,
  011002 (2013); materialsproject.org), licensed under the Creative Commons
  Attribution 4.0 International License (CC BY 4.0,
  creativecommons.org/licenses/by/4.0/). The two *_pseudo files are
  modified: group-averaged pseudo-parent structures derived from them.
- Molecule geometries from PubChem (National Center for Biotechnology
  Information, pubchem.ncbi.nlm.nih.gov): crystod/examples/43_molod/
  XYZ_C6H6.xyz is the 3D conformer of benzene (PubChem CID 241), and
  XYZ_O2.xyz (in crystod/examples/42_molecular_salc, 43_molod and
  test_XYZs) was converted from an SDF record of O2 obtained from PubChem.
