Spectra as a function of position in the cloud. The (0, 0) position refers to the cross in Fig. 3. The “peak” position corresponds to the triangle in the upper right panel of Fig. 3. The “high-vel” position corresponds to the triangle in the upper left panel of Fig. 3. The “low-vel” position corresponds to the triangle in the lower right panel of Fig. 3. The y-scale varies because the spectra are expressed in Jy/beam so the larger beams have greater fluxes. The tapered and untapered spectra are shown in the same order as in Fig. 2.
