The NSF proposal is submitted. It is about—among other things—a trust model for the VO. I think whether or not we get funded, Lang and I should write this up as a short paper, since we figured a fair bit out about the issues. Not sure if that's an LPU though. Spent a good deal of time with Bovy, briefing him on what I got from the Gaia meeting last week, and strategizing about BOSS target selection, where it seems like maybe we should make a firm proposal for being the primary algorithm. In related news, Jessica Kirkpatrick (Berkeley) was visiting today (and will be back next week for SciCoder).
