Retrieved spectra with the JWST MIRI JexoPipe data. The solid curves show median retrieved spectra obtained from the POSEIDON retrievals on MIRI JexoPipe data for the CH₄ + CO₂ baseline, and the canonical models for each of DMS and methacrylonitrile, the two species which are most preferred against the baseline model, when considering all cases described in this work. Also shown are the JExoRES and JexoPipe MIRI observations.
