Observations of C 18O ( J = 1 - 0) emission spectrum in the dark cloud L 1211

We observed, for the first time, the C ¹⁸O ( J = 1 - 0) emission line in the dark cloud L 1211 and found broad wings in the line in the compact core of the dark. We present a two-dimensional atlas of the spectral profile and maps of integrated and partially integrated intensities.

13 velocity-longitude and velocity-latitude diagrams are also given in the original article. These, and some partially integrated intensity maps are not included in this translation to save space
