I put more exercises into my MCMC document, and put another figure into my single-photon microscopy document. I had a long conversation with Hans-Walter Rix about all the projects we can do with our results on detailed abundances from The Cannon for stellar clusters and in the Milky Way disk.
In the afternoon I started preparing for two Gaia Sprints. These are going to be hack weeks in which we try to exploit the Gaia first data release data in the late Summer and early Fall. The idea is to produce publishable science in one tough week. Watch this space for an announcement soon.
