Table 1. Unit-cell lattice parameters determined by automatic mode for the diffraction pattern under the conditions discussed in Fig. 5 ▶ .

The values for and were held constant at 90 for all cases and are thus not listed. With the space group correctly identified, the deviation of unit-cell length c from its actual value changes from over 6 to less than 0.1. Values in italics indicate the difference from the value reported by Loo et al. (2010 ▶).
