Distributions of redshift (left), F444W flux density (middle), and F1500W flux density (right) for the full sample (N = 443) and the sub-sample with robust PAH mass fractions (N = 216) defined as those with q_PAH error < 0.5% or q_PAH parameter constrained by > 3σ from the SED fitting (Section 2.2). The sample is purely star-forming with AGN and quiescent galaxies removed (Section 2.2).
