a. The dust temperature is adopted from the temperature of COMs (CH3OCHO, C2H5CN, and CH3OH) calculated by Qin et al. (2022). The temperature selection for each source is: prioritize CH3OCHO if available, otherwise select C2H5CN, and choose CH3OH if it is the only one present. The same selection criteria apply to Table C.2, Table C.3, and Table C.4.
