Angle-domain parameters computed via weighted slant-stack

Transformation of the off-diagonal terms

In the final example, I show, for the zero-angle section, off-diagonal terms after the transformation to the angle domain. As previously mentioned, it is still not clear the way this results can be used to correct for illumination problems. According to the initial interpretation of the results shown in Figure 10 it is clear that off-diagonal terms start gaining importance as we approach the flank of the salt body at the right of the section. All the transformed diagonals were scaled to the same value. Actually, the rms value of the main diagonal is approximately 20 and 180 times higher than the rms value of the 5th and 15th off-diagonal, respectively.
