We combine our high-sensitivity southern HI survey with the Leiden/Dwingeloo Survey, considering l=240°-400°, b=-60° to +60°, and radial velocities of V=-41.8 to +40.8km/s. We point out the main HI branches surrounding the association and derive their kinematics. Kinematical HI-maps were compared with spatial maps of interstellar (IS) NaI from the literature. Upper limits for distances d were derived from optical IS absorption components from the literature. Models of expanding spherical HI shells were fitted around each stellar subgroup. Description: In this paper we are using our new high-sensitivity southern 21-cm line survey (see Arnal et al., 2000, ASP Conf. Ser., 218, 401), combined with the Leiden/Dwingeloo Survey of Galactic Neutral Hydrogen (Hartmann & Burton, 1997, Atlas of Galactic Neutral Hydrogen (Cambridge Univ. Press)). File Summary:
