Line profiles of all identified species in HIFI spectral survey of AFGL 2591. Molecules (e.g. HCl, CH) for which hyperfine components were detected are plotted all together and are centred on the velocity of the middle line. Lines with multiply profiles (e.g. CO – envelope and outflow components; HF – emission and absorptions) are also presented in one figure and are centered at the velocity of the envelope component; please compare with Table A.1.
