I learned from Brant Robertson (Arizona), on twitter (tm) of all places, that the LSST level-2 data products will include probabilistic information about source redshifts. I spent some time working out how a "LSST customer" might use those data products. Most of the simple ideas one might have (weight by p(z) at each redshift, for example) are dead wrong and will wrong-ify your answers rather than make them more accurate. Now I am thinking: NSF proposal?
