Line profile for CH3CH2CCH toward TMC-1 from stacking the signal from the transitions of this species in the 31−50 GHz frequency range. The abscissa corresponds to the local standard of rest velocity. The ordinate is the antenna temperature, corrected for atmospheric and telescope losses, in mK. The observed spectra from the individual lines are shown in Fig. B.1.
