Abstract
Summary
We show how the method recently proposed in Messud et al. (2017 ; 2017b) allows consideration of “resolved space” tomographic uncertainties which are complementary information to the total tomographic uncertainties. Resolved space uncertainties are obtained by restricting the tomography model space to the one that can be resolved by tomography. Total uncertainties mostly quantify the illumination uncertainties, whereas resolved space uncertainties tend to be more correlated to the final tomography model. We illustrate how those two uncertainties give complementary information for the subsequent seismic interpretation.
