To establish the connection between galaxies and UV-detected absorption systems in the local universe, a deep (g90% completeness over a >1Mpc region down to <~0.1L luminosities at z=0.3L is consistent with unity inside one virial radius and declines slowly to >50% at four virial radii. On the other hand, passive galaxies have lower covering fractions (~60%) and a shallower decline with impact parameter, suggesting that their gaseous halos are patchy but have a larger scale-length than star-forming galaxies.
