... The algorithm has been successfully applied to both real and simulated astronomical data (Jefferies , 1993; Jefferies 1993) and its ability to accurately preserve photometry in the observed image has been demonstrated. ... In order to investigate the algorithm's performance without the influence of detector and photon noise we took the ``truth'' data set and convolved it with the given PSF to generate a noiseless image. ... The restored object and the two restored PSF's are shown in Fig. ...

. This wide-angle image (spanning 320 miles [510 km]) shows different compositions in the material on MercuryтАЩs surface. The camera used three of the 11 filters available to take this image. (The wide-angle camera can image in 11 filters across the range of visible to near-infrared radiation.) This image combines data taken at 1,000 nanometers (red), 750nm (green), and 430nm (blue) to create a color image.
