Figure 4
High-resolution [ ≥ 0.8 Å−1] residual density maps for a second water molecule before (a) and after (b) modelling of the anharmonicity features with third-order Gram–Charlier parameters. Maps computed with reflections fulfilling the I ≥ condition; linear 0.03 e Å−3 contours; blue solid lines – positive values, red dashed lines – negative values.) |
