Diagram of H i clouds distributed along the FG and BG quasar LOSs. Circle sizes scale with the H i column density such that twice the area represents eight times as much N(H i) (Area = N(H i)^1/3). Low column density clouds, for which no metallicity is measured, are dark blue, while brighter, greener colors indicate clouds with higher metallicities. Zero velocity is at z = 2.6894.
