Simulations of a point-like accretion element (top) and scattered light element (bottom) and the significance of the Gaia DR2-DR3 proper motion anomaly they induce (|Δμ|/σ|Δμ|). Black dashed lines indicate the conservative range where YSO accretion (l<0.5, separation <10 R⊙) and scattered light (any period, l<0.01) are observed.
