Components of phase velocity, group velocity, and wavevector computed by raytracing for the frequency ω1 = 3 × 10-3 mHz. The corresponding raypath is shown in the top panel of Fig. 10. The velocities are expressed in cm/s and the wavevector components in cm-1. We observe that the ratio between kr and kh is about 102, which explains the almost circular spiral observed in Fig. 10.
