Top row: proper motions of photometry-selected stars along the Jhelum stream (left panel) and in a control field (right panel). Bottom row: similarly, color–magnitude diagrams of stars selected on proper motions. Photometric and proper-motion selection boxes are shown in light orange. Jhelum stands out from the Milky Way field population in proper motions as a retrograde stream, and in the color–magnitude diagram where its main sequence is more metal-poor than the field, and is accompanied by blue stragglers (medium orange) and blue horizontal branch stars (dark orange).
