Examples of the Gaia-Sausage-like features in the (V_R, V_ϕ) plane for all M31/MW HESTIA galaxies. Each panel corresponds to different merger remnants in the range |z|> 1 kpc and (1 − 3)R_d where R_d is the disc scale-length from Libeskind et al. (2020). The merger accretion lookback time (Gyr), the total stellar mass of the merger debris at the time of the merger (log₁₀(M_*/M_⊙)), and the stellar mass ratio (μ_*) relative to the main M31/MW progenitor in the time of the merger are given at the bottom of each panel.
