Overview of template spectra and lines, continued in Fig. 3. Before plotting, the segments were normalized individually, each divided by a constant factor, which is the average flux of that spectrum as integrated over the wavelength range of the plot. Then, multiplicative offsets using a factor of 1.5 were applied for clarity. Vertical lines and legend: Identified lines and species. Dashed black lines: Unidentified lines (UID). Sparse dotted black lines: End of a MIRI MRS band, where changes in the spectral resolution occur. We note a peculiar detail, namely broad absorption or emission or artifact features around 7.0 µm near the Aril line, which remain unidentified. The oscillations in the top panel are a good example of remaining fringes even after the fringe flat and residual fringe corrections in the pipeline.
