Distributions of the SFR ratios (SFR^NRK/SFR^SED) in different bins of NRK_ssfr. The distribution are renormalized to unity. The top panel refers to the 24  μm sample while the bottom panel includes all galaxies with K ≤ 23.5 and more massive than M ~ 2 × 10⁹ M_⊙. For each interval of NRK_ssfr, we report the fraction of objects (f_Tot), catastrophic failures (f_Cat), the median (Δ) and dispersion (σ).
