Left Panel: The GALA-generated mock-tidal streams are shown in the Galactocentric frame (MW center is shown as the gray filled circle), where the black-bordered green-filled star is the position of NGC 6569 at the present epoch coordinates X, Y, and Z, are (2.303, 0.087, −1.229) kpc. Our position is shown as the Sun symbol. GALA was set to have star particles ejected every 0.5 Myr for 2.0 Gyr. Y. Chen et al.’s (2025) mock-stream star particles are color-coded by the HRV (right color bars), and M. A. Fardal et al.’s (2015) star particles are shown as the gray dots. Right Panel: The relative number histograms are shown for the J18-observed CaT-sample stars (heavy black outline), the Chen mock-stream star particles (aqua shading), and the Fardal mock stream (sand-colored shading), released in the last 0.5 Gyr, having our AAT-selection of PM, and found in our FOV. The inset shows the orbit for the last 0.5 Gyr, with the motion shown by the black arrow above the star cluster (black-bordered green star). The cluster was last at pericenter ∼48.5 Myr ago.
