Latitude-velocity diagrams of H I brightness around six background targets used for mm-wave molecular absorption studies, using H I data from the LDSS survey (Hartmann & Burton 1997). The spatial resolution is 35′ and the diagrams were constructed at the nearest longitude on the 0.5° grid of the survey datacube. The latitudes of the sources are marked. The line of sight toward B0415+379 (3C 111) is not discussed in this work.
