Correlation of the best-fitting model parameters obtained with our outflow modeling scheme (see Appendix E.1) with the stellar mass of each galaxy, derived via SED fitting (see Sec. 2.2). The plots are color coded by the size of the Mg II halo of each galaxy, reported in Sec. 4, with green colors indicating halos in the extended regime of the distribution, and pink colors indicating more compact halos. The blue squares in the top-left panel indicate galaxies with a more robustly constrained τ₀. For R.A., we only included galaxies with non-isotropic outflows (O.A. < 75°), and for P.A., we only considered galaxies with non-isotropic outflows (O.A. < 75°) that are also not seen nearly face on (R.A. < 75°).
