Smithsonian Astrophysical Observatory Memorandum To : From Date: Re: M. Cappi, Strong Gravity SDT/YB Team, XMS team : M. Garcia April 14, 2010 XMS high/mid/low resolution event rates for bright AGN mrg-2010-02v2 This memo arises out of the concern that the bright AGN that will be used to observed strong gravity effects ­ in particular those for which time-resolved measurements of test particle orbits will be made ­ may generate counting rates in the XMS that are sufficient to overwhelm it. ...

3. Nisenson, et al.: High Resolution Measurements from Power Spectra
Power spectral analysis (PSA) has proven to be an important tool for high spatial resolution measurements from ground based interferometry. ... While many images from HST are far too complicated for PSA, there are a class of scientific problems for which it is a very effective technique for handling the problems created by the HST point spread function. We have been applying PSA to images of gravitationally lensed QSOs, and other objects with some surprising results. ...
