Notes. 1G,2G: fit with one or two Gaussian velocity component(s), respectively; 2Gt: all species fitted simultaneously with the same tight 2-Gaussian velocity profile; (†)the integrated opacity is given for an equivalent hyperfine component of line strength Sul = 1. To obtain column density, multiply the integrated opacity by the corresponding conversion factor α in Table 2. (⋄)Fixed parameter.
