Extended Data Fig. 3: Dynamical properties of stars for a smooth dataset.

From: The merger that led to the formation of the Milky Way’s inner stellar halo and thick disk

Extended Data Fig. 3

a, b, Velocity (a) and ELz (b) distribution, for a dataset obtained by reshuffling the velocities of the stars plotted in Fig. 1a and in Extended Data Fig. 1a, respectively. Visual comparison to those figures shows that these random sets are less clumped than the observed distributions of the Gaia halo stars. Lz and E in b are scaled as in Extended Data Fig. 1, and the colour scale indicates the logarithm of the counts in the bins, with dark red corresponding to the highest number of counts, yellow and blue to 1/5th and 1/15th of this value, respectively, and purple to empty bins.
