Absorption line velocity widths ($\\Delta v_{90}$) are known to scale with host galaxy stellar masses, and inversely with the projected separation from the quasar line of sight. Its dependence on stellar mass can be eliminated by normalising with the emission-line widths of the host galaxies, $\\sigma_{em}$, so that absorbers with a range of $\\Delta v_{90}$ values can be compared directly.
