I continued working on "hot Jupiters as clocks", building a system to find clock drifts. I find that the precision with which a drift is detected is slightly less than I found for the precision of the clock phase or offset; this makes sense, because any drift model has multiple parameters. It took me a while to get good sampling to work (with emcee, and a sensible burn-in schedule) but it now seems to. I can now start searching for signals. Heather Knutson (Caltech) gave me a couple of suggestions.
