t-Plots of the y components of the displacive modulation functions of (a) Nb1 and (b) Nb2 atoms in Ca5Nb4TiO17 (n = 5, filled circles and solid lines) and Ca6(Nb,Ti)6O20 (n = 6, open circles and dotted lines). Circles correspond to atomic displacements in three-dimensional space obtained by commensurate cuts of superspace.
