sim08-make-index-table.py - generates lookup table and a few plots as shown below.

Unit cell

Try to understand crystal symmetry for two unit-cells

1. a=18, b=26, gamma=77
2. a=26, b=18, gamma=77

Presumably maps (qh vs omega) should be the same up to rotations.

Lookup table and maps

Unit cell 1

Unit cell 2

Simulated plot for hq vs omega

Conclusion

• All maps are consistent after appropriate rotation
• almost all lattice nodes can be reconstructed (are included in 2-peak events)
