Future Work

The decay in the residual varies significantly as a function of frequency. At most frequencies the residual decreases only 40% between the first and 40th iteration. It appears that the large values in the residual are dominated by events at the cusp of the mute zone. () faced similar problems when inverting for an image using migration as her linear operator. Introducing a weight function in the frequency domain has the potential to speed up the inversion of both problems.
