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.

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 {in} (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
