The 1σ (darker colored bars) and 2σ (lighter colored bars) ranges of PCCs when comparing all atmospheres of a given archetype for a given planet to the available JWST transmission data for that planet (T-1 b, c, d and e). The bars with filled and unfilled circular points denote atmospheres without and with the addition of trace SO₂, respectively. The dotted horizontal gray line shows where PCC = 0; points that fall above that line indicate a positive correlation and points that fall below indicate a negative correlation to the transmission data.
