VizieR Online Data Catalog: Radio Molecular lines in infrared dark clouds (Ragan+, 2006)

We mapped 41 of the sample of MSX dark clouds in emission from C¹⁸ J=1->0 (nu=109.782GHz), CS J=2->1 (nu=97.981GHz), and N₂H⁺ J=1->0 (nu=93.173GHz) using the 14m Five College Radio Astronomy Observatory (FCRAO). The observations were made in 2002 February, May, and December using the 16 element focal plane array receiver SEQUOIA.
