11. Samples of widely different size with the same aspect ratio yielded closely similar results, confirming the validity of our analysis.
12. Crystal structures have not been systematically measured as a function of temperature. In the absence of a change in phase, the lattice parameters are found to be about 1% smaller at 100 K than at room temperature, and the relative difference in c / a is expected to be much lower; we therefore assume that c / a is a constant.
