abstracts, image modeling

I worked on abstracts for the Koposov and Wu papers that are being finished now in Heidelberg. Abstracts are the hardest parts of papers and therefore should be written first and constantly tinkered with as the paper is written and revised.

Marshall and I developed a plan to start image modeling, with the goal of finding faint lensing galaxies under the flux of bright, multiply-imaged quasars. This problem is a hard one in ground-based data, but essential if the lenses from PanSTARRS and LSST are going to be properly mined. The project is related to the image modeling projects of Lang and Bovy and myself; Marshall and I are hoping that we can join forces somehow. Among other big issues: Can we believe the surveys' pipeline-output PSF models, or do we have to fit for a set of perturbations or modifications around or away from those outputs? If we do have to fit, what basis functions make most sense?
