Notes. In those cases where the associated errors are zero, the parameter was fixed. Synthetic fits do not give errors in the integrated area. Remarks: (b) blended line; (m) multi-transition line. The parameters refer to the main component of the group; (s) synthetic Gaussian fit using MASSA; (hf) hyperfine transition; (i) line coming from the image band. See Appendix A for more details.
