Notes. 
is the peak temperature of the line, v0 is the centroid, and vFWHM the line width. The quantity 
and the area are directly measured from reading the spectral data. The quantities vFWHM and v0 are measured by modeling the line either by a single or double Gaussian function that best fits the data. When two Gaussian functions are needed to model the sum of the signal emitted by the ambient cloud and structure of interest, we discard the contribution of the ambient cloud and only take into account the parameters v0 and vFWHM associated with the broad component. The asymmetric high-velocity wings of 12CO lines corresponding to the shocked clump require two Gaussians, thus we measure v0 = (c1 + c2)∕2 and 
where c1, c2, σ1, and σ2 are the centroids and standard deviations corresponding to each Gaussian function, respectively.
