On the airplane to Seattle for AAS 217, I prepared my talk slides. It is a 15-minute talk (number 206.04 if you are at the meeting), with the following summary:
- Catalog matching is not a good way to combine imaging data sets
- (the Right Thing To DoTM is build a simultaneous model of everything).
- Forced photometry is a great approximation when one data set is better
- (one data set is deeper and higher in angular resolution).
- SDSS has this property relative to GALEX.
- A typical quasar in SDSS is not clearly detected in GALEX
- but nonetheless GALEX helps us find them,
- GALEX photometry at < 5 σ can provide photometric redshifts,
- and GALEX measures at high signal-to-noise their average properties.
- We use this framework to measure the extragalactic UV background.
