chatting

I spoke briefly with Chris Ick (NYU) about quasi-periodic oscillations in Solar flares, Megan Bedell (Flatiron) about telluric lines in stars observed with HARPS, and Adrian Price-Whelan (Princeton) about finding overdensities in the halo in Gaia DR2 data. With Ick we discussed whether to use the Bayesian evidence or a parameter estimate to compare nested models. My loyal reader knows which side I was on! With Bedell we discussed how we might verify that our telluric model is good, using line covariances. With Price-Whelan we discussed how to estimate local overdensity in both position and proper motion that would be maximally sensitive to streams and the like.
