Notes. The coefficients of the best fit lines in Fig. 12: F3.3 PAH = 10a⋅log(Excess) + b, where Excess is a value on the x-axis, the flux difference measured in the JWST filters covering the 3.3 μm PAH feature and its neighboring filters (see Sect. 5.3.2 for more details). The JWST filters, which cover the 3.3 μm PAH feature and the filters used for estimating its local continuum at each redshift, are also listed.
