Extended Data Fig. 2: Radial profiles of ionic column densities.

Measured column densities of Magellanic components at v_LSR > 150 km s⁻¹ as a function of the LMC impact parameter, ρ_LMC, with open circles marking upper limits in a. For each ion, the best-fit line and uncertainties are found using a Markov chain Monte Carlo analysis with censoring, as in Fig. 2, for all impact parameter for low ions and only ρ_LMC > 7 kpc for C IV and Si IV. Each panel corresponds to the ion labelled in the lower left. b, A comparison of C IV column densities as a function of impact parameter normalized by the radius enclosing a mean overdensity of 200 times the critical density, R₂₀₀, of the host galaxy with the COS-Dwarfs survey²³ and M31 (ref. ²⁴). The LMC data use R₂₀₀ = 115 ± 15 kpc.
