Histograms of the mean-square displacements, summed over all k and mode sets (j) for 240 ensembles for each symmetry operation of P4mm. (a) The identity E, (b) a vertical mirror along x, σv, (c) a twofold axis, 2C4 = C2, (d) a vertical mirror and twofold axis σv + 2C4, (e) a vertical mirror plane along xy, σv + C4 = σxy, (f) the fourfold rotation axis C4 and (g) 3C4. |
