Velocity distributions of Gaia DR2 GSE stars selected with eccentricity e > 0.7 and restricted to the ROI (black histograms), shown in spherical coordinates: radial (v_r, left), azimuthal (v_ϕ, center), and polar (v_θ, right). For comparison, we show results from previous studies: L. Necib et al. (2019a; solid yellow), L. Lancaster et al. (2019; dashed turquoise), N. W. Evans et al. (2019; dashed-dotted blue), L. Necib et al. (2020; solid orange), and C. A. J. O’Hare et al. (2020; dotted green). The distributions of our selected GSE stars are largely consistent with those reported in earlier works.
