For 61 stars whose interstellar Lα absorption was observed by OAO-2, the average relation of H I column density to B – V color excess is equal to 5 × 1021 atoms cm–2 mag–1. For a recent dust grain model this value implies that the density ratio 〈ρHI/ρdust〉 ≈ 100. A good correlation was found for deviations in the measurements of NHI and E(B – V) from their mean values expected over the distances to the different stars, indicating an association of H I gas with dust.
