Notes. General notes to Appendix B tables: (i) Frequency, energy of
the upper level of each transition (
), Einstein coefficient for
spontaneous emission (
), intrinsic line strength
(
), and the level degeneracy
(
) from MADEX. The
velocity-integrated intensity (
), radial velocity
(
), and FWHM line width
(Δv) obtained by Gaussian fit. (ii) Parentheses
indicate the uncertainty obtained by the Gaussian fitting programme. The fit
uncertainty in units of the last significant digit is given in Tables B.1, B.6, and B.8. (iii) The weighted
average of hyperfine and fine components is used for the analysis of
C2H,
l-C3H, c-C3H, and C4H molecules. (iv) Fully
overlapping transitions are marked with connecting symbols. (v) We note that the
line intensities in Tables B.2, B.4, B.5, and B.7 are given in units
of mK. (vi) Labels:
