Notes. For the sources with “HFS” in Col. 2, the line’s hyperfine structure has been fit, and the same output parameters in Cols. 2–6 of Table 3 are given in Cols. 3, 5, 6, 7, 9. For the sources with “G” in Col. 2, the satellites of the (2,2) line are undetected, so that the main group of hyperfine components has been fit with a single Gaussian. For these objects, we give integrated area (in K km s-1, Col. 4) and peak intensity (in K, Col. 8) of this Gaussian, respectively. For the sources marked with a “T” in Col. 2, we clearly detect the satellites in the (2,2) transition, and performed a good fit to the hyperfine structure, but the line is optically thin. In Col. 8 we also give the peak temperature of the main group of hyperfine components, which is the parameter used to derive the NH3 total column density in this case (see Sect. 3.1.2). The uncertainties of all parameters are in parentheses.
the spectrum shows two velocity components (Fig. A.2). Only the fit to the stronger component is shown;
the spectrum shows two velocity components (Fig. A.2). Fontani et al. (2004) also found these two components in C18O and attributed the one centred at ~–50 km s-1 to the HMPO. Only the fit to this component is shown.
Tex2,2 cannot be estimated. For these objects, in the calculations described in Sect. 3.1.2 we have assumed Tex2,2 = Tex1,1.
