Astrometric positions of stars associated with nebulosities in the southern hemisphere. Several stars associated with nebulosities and cited by S. van den Berghand W. Herbst are included in the preliminary programme for theHIPPARCOS mission. When performing preparatory measurements of plates,we encountered difficulties in identifying certain of these objects whenrelying only on coordinates, which led us to take advantage of thiswork, which relates to the southern sky, in order to determine theastrometric position of all the objects in the list, to within 0.35''.This catalogue is available from the Centre for Astronomic Data atStrasbourg.
