Projected distance between satellite and assumed host galaxy in kpc vs. recessional velocity difference between satellite and host (ΔV = V_sat − V_host) in km s⁻¹. The projected distance and velocity difference to the host assumed in MATLAS are plotted (gray circles) compared with the updated host based on minimal ΔV through MUSE spectral fitting (red points). These shifts are indicated by black arrows. For the red points circled in gray the assumed host stays the same with new velocity information on the dwarf. The dashed black lines show ±300 km s⁻¹.
