Notes. The values of λ, w, and W are from Galazutdinov et al. (2017). Values between parentheses are measurement errors. (a)Consistent with 9 × 1012 cm−2 toward HD 169454 and 20 × 1012 cm−2 toward HD 183143 in Berné et al. (2017). (b)Consistent with 2 × 1013 cm−2 in Walker et al. (2015) and (2 ± 0.8) × 1013 cm−2 in Campbell et al. (2016b).
