A catalogue of dust clouds in the Galaxy Dutra C.M., Bica E. <Astron. Astrophys. 383, 631 (2002)> =2002A&A...383..631D
ADC_Keywords: Interstellar medium ; Nebulae, dark; Reddening ; Morphology Keywords: ISM: clouds - Catalogs Description: The file cdn.dat is an unified dust cloud catalogue of the Galaxy. Considering an initial list of approximately 6500 entries we condensed them into a cross-identified all-sky catalogue containing 5004 dust clouds. File Summary:

Note (1): Notes: (i) distances in kpc preceded by `d='; (ii) CO or HI LSR velocities preceded by `vCO=' or`vHI=', respectively; (iii) hierarchical relations among dark and/or bright nebulae (e.g. LBN for Lynds, 1965ApJS...12..163L and Sh2- for Sharpless, 1959ApJS....4..257S), as indicated by ∈ (within), {inc} (includes) or {rel} (related). Note that dust cloud designations are not mixed to those of bright clouds, since such possible relations are given only in this column
