Phil Marshall (UCSB) came into town to talk about various things, including image modeling or deconvolution. We are both trying to reach the information limit in ground-based data by image modeling. Marshall's problem is to find or analyze arcsecond-scale gravitational lenses in large ground-based surveys where the seeing is on the order of one arcsecond. My problem is to create the best possible astrometric catalog from multi-wavelength data from NASA surveys. In both cases, we need to fit point sources to our images; this is deconvolution (even though most wouldn't call it that).
