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 1965ApJS...12..163L and Sh2- for Sharpless,
1959ApJS....4..257S 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
