Data selection. Left panel: Gaia CMD of the selected LMC targets with 3D kinematics (blue). Middle panel: PM vector diagram of the LMC sources with 3D kinematics, colour-coded by the LOS velocity. Right panel: Same as the middle panel but colour-coded by the μ_RA μ_Dec correlation coefficient. The grey points in all panels show additional LMC sources with good Gaia PM measurements (μ_err < 0.1 mas yr⁻¹) but no LOS velocity entries. These are the sources used in our 2D Jeans model.
