Fig. 8
CH emission and absorption towards W3 IRS5. Top panel: λ560 μm line (HIFI/PRISMAS). Bottom panel: λ149 μm (upGREAT). The red lines indicate the commonfit to both spectra (in the χ2 sense). The hyperfine splitting is indicated by blue markers, scaling with the corresponding weight for a complete ground-state level population. The strongest hyperfine component of the λ560 μm line is centered close to the systemic velocity. For details see text.
