Conditions
- Dielectric provenance: kappa11 and kappa33 were fixed to averages of the values in the paper's Refs. 27 and 30.
- Orientation: x1, x2, x3 are parallel to [10-10], [-12-10], and [0001], respectively, using the paper's standard 3m setting.
- Specimen: Oriented monocrystal, 5.039 mm x 5.070 mm x 4.973 mm.
- Symmetry: 3m
- Temperature: 30 +/- 0.02 degC for the resonance measurements
- Uncertainty: Table III reports coefficient-specific uncertainties; average diagonal stiffness uncertainty is 0.09% and average piezoelectric uncertainty is 5%.

Troubleshooting
Do not extrapolate a constant or tabulated value outside its stated conditions without justification. A material name alone does not establish suitability for your experiment.
