Eilers (MPIA) and I went on the APOGEE science telecon to describe our results. I talked about how we calibrated a (purely linear) spectro-photometric distance estimate for luminous red giants that manages to correct for dust and luminosity, and Eilers talked about how we used those tracers to measure the circular velocity of the Milky Way disk (that is, the potential). We use the Jeans equation in cylindrical symmetry. We got great feedback from the APOGEE team, which we will use to improve our discussion in our papers.
