Same as Figure 4, but for the sums of each component shown. Models 1 and 2 are EGRB from all star-forming galaxies (quiescent plus starburst), with two different spectra for starbursts. To show the effect of intergalactic absorption, Model 1 without absorption (thin solid line) and the cascade component of Model 1 are also shown. The total of star-forming galaxies plus AGNs is also shown using Model 1 for star-forming galaxies.
