File Rayleih.txt contains local Rayleigh wave group velocities obtained by Filippova and Solovey (2022) using a surface wave tomography method by Yanovskaya and Kozhevnikov (2003). The group velocities are listed at different periods from the range of 10-250 s: 10, 15, 20, 25, 30, 40, 50, 60, 70, 80, 90, 100, 125, 150, 200, 225, and 250 s. Region: 64-72 N, 26-40 E.

Column description:
1 - longitude (deg.)
2 - latitude (deg.)    
3-18 - Rayleigh wave group velocities (km/s) at the periods indicated at the top of each column.
