Notes. † The square brackets for the second component along the line of sight towards ρ Oph A indicate that the dust depletion measurement for this component is unconstrained due to the saturation of most metal absorption lines. 1 Distances are from the Sun and taken from Gaia DR3 (Bailer-Jones et al. 2021). 2 Valencic et al. (2004).
