Notes. Columns show modeled excitation temperature (Tex), column density (Ncol), line width (Δv), and line velocity (vLSR) for each of our key species. The columns indicated by a minus sign (−) indicate the error to the left of the result and those indicated by a plus sign (+) indicate the error to the right.
