Abstract

The maximum entropy method is applied to Hubble Space Telescope data taken of the R Aquarii binary system and its jet with the Faint Object Camera in order to restore an image in [O III] at 5007 Å plagued by spherical aberration and detector saturation. These results are compared with 2 cm radio continuum imagery taken with the Very Large Array at the same limiting resolution of ∼0″.1. The comparison suggests that shock excitation of the inner jet accounts for a spatial difference between the [O III] and radio continuum emission regions.
