Simplified analysis of the 6 and 6.8 µm bands of Ced 110 IRS4A using laboratory data. H₂O ice is not subtracted in this case. Panel a shows the sum (green) of four laboratory spectra of known species. Panel b shows the fractional area of each component relative to the total area in the MIRI spectra between 5.5 and 7.5 µm. Unidentified refers to the difference between the MIRI data and the sum of the four components in the specified range. The contribution of NH₃:CO₂ is not added to the chart because it represents less than 1% of the total area.
