Real part of P (a) [|${\varepsilon _{\rm TH}}$| (solid lines, labelled as Re(|${\varepsilon _{\rm TH}}$|)) and |${\delta _{\rm TH}}$| (dashed lines, labelled as Re(|${\delta _{\rm TH}}$|))] and S (b) [|${\gamma _{\rm TH}}$| (solid lines, labelled as Re(|${\gamma _{\rm TH}}$|))] wave anisotropy parameters with frequency under effective pressures of 20, 40, 60, 80 and 100 MPa. Note that the real part indicates the velocity anisotropy.
