Figure 3

Reciprocal space sections at 100 K with \(a\sim 4.1\) Å, \(b\sim 7.1\) Å, \(c\sim 8.45\) Å, \(\alpha =\beta =\gamma =90^\circ \). The picture shows main (green) and satellite (blue) reflections. For comparison the supercell unit-cell (SC) 3a × b × 2c (red) and the hexagonal sublattice (magenta) are given.
