multiple stellar populations in the disk

Eilers and I looked at the dependence of the kinematics of disk populations with various element-abundance ratios. And we built a model to capitalize on these differences without binning the data: We parameterized the dependences of kinematics (phase-space distribution function) on element abundances and then re-fit our dynamical model. It didn't work great; we don't yet understand why.
