modeling galaxies with galaxies

I spent a long time on the phone with Lang, who is building quantitative models of galaxy images using other galaxy images. We spoke about the free parameters, and the robustness of the fitting (given that there are some random superimposed stars and the like), and so on. He has some nice results already, and this has only been underway for a few days now. At the end of the day I gave a big public talk here in Buffalo.
