- Slide 1: ../PFOpol.gif Fig. 12. Initial polarization direction of PFO data compared to radial direction. A) Minimum tangential, variable initial polarization method. B) Maximum cross-correlation method.
- Slide 2: ../PFOerror.gif Fig. 13. Whole-suite error surfaces (contours) for several methods for estimating one-layer splitting parameters, with individual-seismogram estimates (circles). A) Minimum tangential component method with fixed initial polarization. B) Minimum tangential component method with variable initial polarization. Maximum cross-correlation method. D) Cross-convolution method.
- Slide 3: ../PFOazi.gif Fig. 14. Estimates of the azimuth of the fast direction for several one-layer methods. A) Minimum tangential, fixed initial polarization method. B) Minimum tangential, variable initial polarization method. C) Maximum cross-correlation method. D) Cross-convolution method.
- Slide 4: ../PFOtest.gif Fig. 15. Result of general 2-pulse operator applied to one-layer synthetic. (A) Testing the ratio, b1/sqrt(a1^2+a2^2), of coefficients (circles) against the predicted value of sin*cos (line). (B) Testing the ratio, -b2/b1, of coefficients (circles) against the predicted value of unity (line).
- Slide 5: ../PFOerror2.gif Fig. 16. Whole-suite error surface for two-layer cross-convolution method, as a function of the azimuth of the fast axes of the two anisotropic layers. All regions where the error is greater than the best-fitting one-layer solution are shown in white. Darker grey shades correspond to smaller error.
