Azimuthally averaged power of a fully restored hyperspectral cube at 6302 Å. The plot shows the power for an image that is an average over 1, 2, 8, 32, and 64 continuum wavelength positions. The arrow indicates the spatial frequency where the S/N is unity, beyond which the deconvolved noise overwhelms the image information. Averaging over more wavelength positions reduces the noise, but not the image information, shifting the point where the S/N is unity to smaller spatial scales.
