responding to referee; the disk

I spent the day in Princeton; the morning with Bovy talking about the Milky Way disk and the afternoon with Lang working on the response-to-referee on the Comet Holmes paper. We are very, very behind schedule on that! We made figures that compare the Comet Holmes orbit we inferred to the NASA orbit. We don't get quite the right orbit, in part because our model of the data we scraped from the web is so crude.

Bovy and I discussed his results on the kinematics of mono-abundance subpopulations in the Milky Way disk, a follow up to his paper on the spatial structure of those same populations. We also discussed his measurement of the disk rotation curve with APOGEE data; he gets a low-amplitude (relative to Reid and The Colbert Report) rotation curve, which is intriguing.
