using variability to separate overlapping sources

Phil Marshall is in town for two days. We batted around the idea of fitting objects in the SDSS Stripe 82 data that have quasar colors but are marginally resolved. These objects could be gravitational lenses, and we could use the variability as well as our knowledge of the PSF to get them deblended and modeled. We debated whether we should deblend first and interpret second, or do the deblending with the interpretation (quasar-variability model or gravitational-lens model) built in from the start.
