Table:
Anisotropic structure (hexagonal symmetry) consistent with shear-wave
splitting observations at HRV.
``Depth'' indicates the bottom of each layer.
The parameters B and E scale peak-to-peak variations of compressional
and shear velocity, respectively, each with 
azimuthal
dependence [Park, 1996].
The angles 
and 
define the tilt (from vertical) and
strike (CW from N) of the axis of symmetry within each anisotropic
layer.

Table:
Anisotropic structure (orthorhombic symmetry) consistent with shear
wave splitting observations at HRV. Velocity values in anisotropic
layers are the isotropic averages of respective elastic tensors.
The anisotropic medium is modeled as 30% orthorhombic
olivine and 70% isotropic olivine, a mixture that is 
%
anisotropic.
The angles and define the tilt (from vertical) and
azimuth (CW from N) of the symmetry axes (fast, intermediate, slow)
within each anisotropic layer.

Table:
Anisotropic structure (hexagonal symmetry) consistent with P-coda
receiver functions [Levin and Park, 1997a] and shear-wave
splitting observations at ARU.
Depth indicates the bottom of each layer.
The parameters B and E scale peak-to-peak variations of compressional
and shear velocity, respectively, each with azimuthal
dependence [Park, 1996].
