This folder contains the b-spline model for both rayleigh and love wave dispersions. (Ma et al., 2014, A comprehensive dispersion model of surface wave phase and group velocity)

Frequency range:
rayleigh phase: 5mHz-35mHz
rayleigh group: 7.5mhz-40mHz
love     phase: 7mHz-30mHz
love     group: 10mHz-30mHz

Error estimation:
rayleigh phase: 0.6% 
rayleigh group: 1.0%
love     phase: 0.75%
love     group: 1.5%

Files:
getpoint_map.1.f:  input long and lat, output phase and group velocities at an interval of 2.5mHz in file point.1 
xval.map and xval.prem:  the actual bspline coefficients. these are binary files
