Stars within Gaia DR2 with δϖ/ϖ < 0.10. These stars have been identified as accreted by our neural network using 5D kinematics alone. While the HR diagram is shown, photometric information is not used in these selections. As expected for an accreted population, these stars are nearly uniformly distributed in the l, b plane. See Fig. A.1 for the analogous figure for the stars classified as in situ.
