• Model parameters:
  
  • vsv: isotropic shear wave velocity (km/s)
  • unc_vsv: uncertainty for isotropic shear wave velocity 
  • fa:  depth-dependent fast azimuth (deg)
  • unc_vsv: uncertainty for depth-dependent fast azimuth
  • amp:  depth-dependent anisotropy amplitude (%)
  • unc_amp: uncertainty for depth-dependent anisotropy amplitude
