 vphRAY1Zn0_5.tbz (16 Mo) : ASCII file with all the values for phase velocity maps (CLASH) for n=0 to n=5

Global phase velocity maps for fundamental mode and overtones of Rayleigh waves (R1)

n=0, T=50 s

Isotropic perturbations are given in % with respect to the median value used during the inversion (3,977 km/s).

n = 0, T = 100 s

Comparison with the model obtained by Ekström. The same color scale is used for both maps, the stars represent the known hotspots.

n = 2, T = 150s

Comparison with the model obtained by van Heisjt & Woodhouse (1999). Two different color scales are used, the stars represent the known hotspots.
