Histograms show reflex-corrected proper motion dispersions in the Magellanic Stream coordinate system (L, B). We have normalized the histograms such that their areas integrate to unity. The black-lined histogram corresponds to pixels bound by the polygon in Figure 12 and the dashed-line histogram is stars bound by the aperture described in the text. The gray histogram represents the metal-rich pixels in the LMC bar region ,which are distinctly hotter than the two disk populations. Stars in the Southern Arm appear to share similar dispersions to those lying at a similar (projected) radius across all azimuthal angles.
