no short-cuts for planet searching?

I came in early to do some writing with Megan Bedell (Flatiron). We are so close to having her paper on the wobble software for data-driven modeling of HARPS spectra done! The results are just incredible and amazing. Can't wait. I still have to-do items there.

Late in the day I bounced off of Dan Foreman-Mackey (Flatiron) the idea that Price-Whelan (Princeton) and I had about making an effective noise model that would permit us to search for medium-period planets in radial-velocity data without explicitly modeling and marginalizing out the short-period planets. He simultaneously thought the idea was wrong (duh) but that it is an important thing to be thinking about: How do we make decisions about promising stellar targets for RV observations without keeping fully updated posterior or likelihood information about their full multi-planet planetary systems?
