Truth-level Toomre distributions for LSR0 of m12i with δϖ/ϖ < 0.10 and measured v_r. Bright yellow regions denote higher density while the darker blue regions denote lower density, with density ranging from 1–10³ stars/50 (km s⁻¹)². The outer (inner) dashed lines denote |v − v_LSR| > 224 km s⁻¹ (124 km s⁻¹) with v_LSR = (0, 224, 0) km s⁻¹. Velocities are given in Cartesian coordinates centered on the sun, with the x axis oriented away from the Galactic center. Accreted stars are essentially uniformly distributed in this plane, although with structure clearly visible, while the in situ stars peak towards v_LSR, as expected.
