Intensity as a function of wavelength for the total attenuated intensity (gray), and the components of the young stellar (blue), old stellar (orange), and dust emission (red) for two model galaxies: (a) in the top panel is a galaxy with low star-forming activity (SFR = 0.01 M_⊙ yr⁻¹, sSFR = 10^−11.75 M_⊙ yr⁻¹/M_⊙) and low-extinction (E(B − V) < 0.001), and (b) in the bottom panel is a dusty (E(B − V) = 0.55) galaxy with high star-forming activity (SFR = 68 M_⊙ yr⁻¹, sSFR = 10^−8.5 M_⊙ yr⁻¹/M_⊙). The dashed-dotted lines with brown and purple colors represent the WISE bands 1 and 3 transmission bandpasses respectively. The dotted fuchsia and red lines represent the JWST NIR-F200W, and MIRI-F2100W bandpasses respectively.
