Abundances of COMs relative to CH₃CN in the cold and warm components of the envelope. The first row represents the cold component of the envelope with the relative abundances to CH₃CN without size correction (top left panel) and including the correction by the size of the emitting region (top right panel). The bottom row represents the hot component of the envelope with the relative abundances to CH₃CN without size correction (bottom left panel) and with size correction (bottom right panel). Each source is indicated in a different colour. Black arrows indicate upper limits.
