16. In principle, the strain α can be obtained directly from the data for the Bragg wave vector q as a function of electric field E. However, our q vs E data are fairly noisy, so they do not give good-quality fits for the line shapes. For that reason, we assume the relation α=CE and determine C in two ways: from a fit of the line shapes and from a fit of the q vs E data. These two approaches give approximately the same value of C.
17. The mosaicity ξ has a slight field dependence; it varies by approximately 15% over the range of fields investigated. For simplicity, we used a single mosaicity to describe the entire data set and allowed it to vary over this 15% range. This variation affected the quality of the fit, but had no effect on the values of the other parameters.
