In my weekly with Jason Hunt (Flatiron), we discussed the point that if the gaps in the local velocity distribution in the Milky Way are caused by the bar (or some of them are) and if the gaps are purely phase shifts and not things being thrown out by chaos, then the velocity distribution in a localized patch should vary with azimuth as an m=2 pattern, with maybe some m=4 and m=6 mixed in. So, that made us think we should look at simulations, and see if there are any features in the local velocity distribution that might be interpretable in such a model. For instance, could we measure the angle of the bar?
