Peaks detected in the mock Gaia catalog with no Sgr stream. Left: proper motions of the peaks as a function of (top: proper motion in Galactic longitude, middle: in latitude, bottom: total proper motion) color coded by proper motion in latitude (top), in longitude (middle), and by WT scale (bottom). Right: same as in the left panel but in a 2D histogram with the LM10 model superposed with black lines.
