Note:

(f) parameter frozen to shown value; For this observation, the continuum parameters are coupled for clumps 1 and clumps 2, and for shallow-dipping and persistent. The “/” sign indicates that the component is not included.

In the text, we refer to results on cold absorption as hot_loc + hot_gal as discussed in Sect. 3.2.
