Top to bottom panels: on-sky distribution, density, width, and proper motion profiles of the narrow and wide Jhelum components (orange and blue points, respectively). The narrow component has a constant width and density, while in the wide, spatially offset, component both width and density increase toward the leading end (more negative ϕ₁). However, the two Jhelum components have proper motions that are consistent within uncertainties (shaded area). The best-fitting orbit in the standard Milky Way potential reproduces the sky and proper motion distribution of the narrow component (thin line).
