A comparison of the inverse Wiener filter F^-1 used by (Joshi et al. 2011) (dashed line) and our deconvolution with (dotted line), as given by Eq. (5). The left panel displays the two functions, and the right panel displays the power spectra of the uncorrected (solid line) and corrected images. Differences in the power spectrum between the two methods (dashed and dotted lines) are seen to be very small.
