We have identified a mistake in the calculation of the total hydrogen column densities for all eight lines of sight in this sample. In the text of the paper, we report the total hydrogen as N(H_tot) = N(H I) + × N(H₂). However, it should be N(H_tot) = N(H I) +2N(H₂), with the factor of 2 on N(H₂). The effect of this is a slight decrease in metallicities, both for the full line-of-sight measurements, [M/H]_tot, [M/H]_ref, and [M/H]_vol, and the simulations of metallicities of individual gas clouds, [M/H]_i. The only unaffected line of sight is that towards θ¹ Ori C because it has a negligible contribution from H₂. The methodology of the paper remains unaffected, as do all measurements of dust depletion, for both the full line of sight, [Zn/Fe]_fit,tot, and individual (groups of) components, [Zn/Fe]_fit,i. The levels of variations in the metallicities from the simulations also do not change. Therefore, the overall conclusions of the paper remain valid. We still constrain the same metallicities, but these values are slightly lower than presented in the paper. In summary, the consequences are the following:

• The total metallicities along full lines of sight are generally lower, with changes between 0.08 and 0.16 dex, or 17% and 31%.

• This decreases the values of the simulated metallicities by the same margin.

• This increases the number of ‘most-likely’ realisations because there are many more realisations with all metallicities <0.5 dex.

• This broadens the gas fraction ranges for all ‘most-likely’ realisations.

In Table 1, we show the updated values and quantify the differences, in terms of both a percentage and dex increase. We reproduce Tables 5, 6, 7, and 8 from the paper for the impacted lines of sight in Tables 2, 3, 5, and 4, respectively. In Appendices A and B, we include the updated figures for the abundance patterns and simulated metallicities, respectively. In Appendix C we include the comparison-to-literature plot with the updated metallicity values for the full lines of sight.

We have also noticed that Fig. 7 in the original paper, which shows the realisations of the most-likely metallicities for the line of sight towards θ¹ Ori C, is not accurate. Figure 1 here is the corrected version.
