Wavelength Dependence of the ACS Coronagraphic PSF
Abstract
In principle, the wavelength dependence of diffraction and scattering structure in a space-based coronagraphic PSF can be used to good effect in removing the halo light of the host star (Sparks and Ford 2002). Here, we test application of this ``spectral deconvolution'' method using observations of the double brown dwarf near HD130948A with the Aberrated Beam Coronagraph on HST's Advanced Camera for Surveys.
