WebWe assume that the NGAO relay offers diffraction limited performance over the full NGAO wavelength range. We also assume that while the Strehl provided by adaptive optics correction will diminish at the shorter wavelengths, the core of the PSF is still equal to the diffraction limited image size even for a comparatively low Strehl.

Web(at least in theory). Just as you can fit a single diffraction limited object with a PSF and get the center position, you can fit two or more objects with a collection of PSF’s and get all the center positions. Obviously you would need a ton of photons, but it should be possible. Comment by LSC — November 30, 2006 #
