I spent the weekend completely off the grid. I didn't even bring my computer or any device. That was a good idea, it turns out, even for doing research. I got in some thinking (and writing) on various projects: I sharpened up my argument (partially helped by conversations with various MPIA people last week) that you never really want to compute the Bayes evidence (fully marginalized likelihood). If it is a close call between two models, it is very prior-dependent and isn't the right calculation anyway (where's the utility?); if it isn't a close call, then you don't need all that machinery.
I worked out a well-posed form for the question "What fraction of Sun-like stars have Earth-like planets on year-ish orbits?". That question is not well-posed but there are various possible well-posed versions of it, and I think some of them might be answerable with extant Kepler data.
Along the same lines, I wrote up some kind of outline and division of responsibilities for our response to the Kepler call for white papers related to repurpose in the two-wheel era. I decided that our main point is about image modeling, even though we have many thoughts and many valuable things to say about target selection, field selection, cadence, and so on. When I get back to civilization I have to email everyone with marching orders to get this done.
Rix and I have a side project to find streams or kinematic substructures in Milky-Way stellar data of varying quality. It works by building a sampling of the possible integrals of motion for each star given the observations, as realistically as possible, and then finding consensus among different stars' samplings. I worked on scoping that project and adjusting its direction. I am hoping to be able to
link up stars in big Halo-star surveys into substructures.
