I analyzed the amplitude behavior of angle gather and compared the resulting amplitudes from angle-domain common-image gathers with the amplitudes from offset-ray parameter images gathers in two models with and without AVA effect. Since results from angle gather are smoother and with a shape more similar to the theoretical tendency. I could observe that the angle gather method is not introducing amplitude distortions; therefore, this result gives us confidence about using this method in applications related to AVA analysis. Observed artifacts in offset ray parameter gather affect the picked amplitudes in the near and far offset. Typically, far offset amplitudes are not used in AVA analysis, but, in this case, near offset traces should be muted out in order to do AVA analysis. A next step should use regularization in the inversion process in order to improve the results in offset ray parameter domain.
