Maps of the Sgr stream in the heliocentric distance vs. Λ_⊙ plane. Left panels: RR Lyrae variables from the DR2 4S. Right panels: particles of the LM10 model. Distances in the LM10 model are rescaled by a factor of 0.94 to make the embedded distance scale more consistent with observations. Upper panels: the points are colour coded according to their pmra values, in the lower panels according to their pmdec. Upper right panel: the approximate location of the transitions between portions of the stream dominated by Pcol = 0 (in the immediate surroundings of the main body), Pcol = 1, and Pcol = 2−3 particles (see also Fig. 5) are shown as reference.
