J/A+AS/116/21 J/A+AS/116/21 Extinction toward CrA and Lup C M Andreazza J W S Vilas-Boas Astron. Astrophys. Suppl. Ser. 116 21 1996 1996A&AS..116...21A Extinction dust, extinction ISM: clouds ISM: individual (CrA cloud, Lup cloud) ISM: magnetic fields Star counts technique is used towards southern dark globular filaments situated in the cloud complexes of Corona Australis and Lupus. Tables and maps of the distribution of visual extinction are presented for each filament. Lower limit masses for the filaments and condensations have been estimated and the central coordinates of the condensations are also given. R CrA is the most active star forming region among the filaments studied in this work whereas Lupus 1, with almost the same lower limit of mass, has only a few T Tauri stars and just one young embedded object. The distribution of direction of the magnetic field in the condensations of Lupus, suggests that the condensation morphologies does not have any apparent relation with the magnetic field orientation.
