Variations in the lattice parameter map ([Delta]d/d map) of the [alpha]-SiO2 [\overline 4220] (X-cut) crystal. The map was taken on the dashed area a2 shown in Fig. 4[link](c). The dashed triangle in (a) is the wedge area (i) due to the orientation flats provided by the manufacturer.  [article HTML]
