For technical reasons, Figs. 8 and 9 were printed with incorrect colour separation. To rectify this unfortunate error, the correct Figs. 8 and 9 with the captions are reprinted below.

[FIGURE] Fig. 8. Two-dimensional V-I coherence spectrum (solid line: Lamb mode, dashed curve: f-mode); the colour bar to the right of the diagram indicates the coherence values

[FIGURE] Fig. 9. Two-dimensional V-I phase spectrum; for each colour, the corresponding phase (degree) is given by the colour bar
