An overview of MIRI retrieval results for different pixel shift cases (rows) using 8 pixel wide channels. The left column of each row shows a measured transit spectrum along with the median retrieved spectral model within representative 1σ and 2σ credibility envelopes. The right subpanels show the inferred 1D marginalized posterior distributions for the isothermal temperature (T), DMS, DMDS, and C₂H₅Cl (chloroethane). Critically, different pixel shift selections lead to different preferences for which gases best fit the spectrum and are constrained, with a trichotomy exhibited here between no abundance constraints (shifts 0, 4, and 7), constraints on DMS+DMDS (shift 5), or constraints on chloroethane (shifts 1, 2, 3, and 6).
