Notes. Numbers within parenthesis refer to the datacube used for the analysis of the H I absorption. ( * )To increase the column density sensitivity, we smoothed the cube to a final point spread function (PSF), and binned three channels together, which is why the rms noise is given over channels of 19.9 km s−1 in width; see Sect. 3.1.
