The day started with a conversation with Bedell (Flatiron) about projects that arose during or after the Terra Hunting Experiment collaboration meeting last week. We decided to prioritize projects we can do right now, with residuals away from our wobble code fits to HARPS data. The nice thing is that because wobble produces a very accurate generative model of the data, the residuals contain lots of subtle science. For example, covariances between residuals in flux space and local spectral slope expectations (from the model) will point to individual pixel or stitching-block offsets on the focal plane. Or for another, regressions of flux-space residuals against radial-velocity residuals will reveal spectroscopic indicators of spots and plages. There are lots of things to do that are individually publishable but which will also support the THE project.
