Caption: Figure 7.

Optical depth spectra toward the ALMA continuum intensity peaks. The red line shows the best fit for each spectrum, and the cyan line shows the best fit for the local continuum. Color lines show the components CH4:H2O (blue), OCN− (green), the Gaussian at 1380 cm−1 (purple), and the Gaussian at 1350 cm−1 (orange). Table 4 shows the Gaussian components reflecting the COM absorption bands.
