Left panels: comparison of our IRAC flux densities to literature IRAC flux densities: F(λ₀) /FLIT(λ₀) flux density ratios as a function of our IRAC flux density, F(λ₀), at 3.6 μm, 4.5 μm, 5.8 μm, and 8.0 μm. The average uncertainties are 17%, 17%, 19%, and 17% at 3.6, 4.5, 5.8, and 8.0 μm. Colours distinguish the reference for the literature measurement. Right panels: ratios of WISE flux densities to other MIR measurements (either IRAC, IRAS, or MIPS) as a function of WISE flux density at 3.4 μm, 4.6 μm, 12 μm, and 22 μm. The average uncertainties are 20%, 22%, 15%, and 12% at 3.4, 4.6, 12, and 22 μm, respectively. On all panels, we show the unit ratio as a solid line as well as the average uncertainties on the ratio in each bands as dashed lines.
