Quintero and I worked on focusing his latest paper onto the processes that control the morphology–density and star-formation–density relations.
Rix and I found that we could get an intelligible proper motion distribution as a function of stellar magnitude for what are plausibly turn-off stars in the halo and in the thick disk, inspired by Girard et al. The relative velocity of a typical thick-disk star relative to the Sun increases with distance, but the proper motion involves an inverse distance (because it is an angular measure of motion), so the distribution for the thick disk is very simple.
