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.
