S₁₀₀/S₂₄ as a function of the Herschel derived L_IR over the L_IR derived based only on the 24   μm flux densities. Green circles are sources at 0.2 < z < 0.6 and orange circles are sources at 1.0 < z < 1.7. The top right box (defined by S₁₀₀/S₂₄  >  43 and L_{IR   Herschel}/L_IR   24 > 3) consists mainly of sources at 1.0 < z < 1.7. Vertical dashed lines indicate the area where the two L_IR estimates agree within a factor of 1.5.
