Notes. The table lists the redshifts and neutral gas column densities, N(H I), as estimated from HST UV spectra, as well as the number of galaxies with a redshift matching zabs, totalling to 39 objects. The penultimate column provides the number of ALMA pointings required to efficiently cover all these targets. The ALMA primary beam in band 4 is 44 arcsec, while it is 27 arcsec in band 6.
