Figure 6
t-dependence of bond-valence sums for Ba1 and Ba2 positions in the modulated BTG structure. Values averaged over t and without modulation waves are also plotted. For bond-valence calculations within the non-modulated structure, a cut-off radius of 3.5 Å was used, while in the modulated structure, a cut-off at 3.2 Å was employed.
