Caption: Figure 4.
Total intensity of the far-IR background (CIB) in the BLAST bands associated with 24 μm galaxies is plotted against wavelength. The BLAST error bars include calibration uncertainties and are highly correlated between bands. The point at 850 μm labeled SCUBA is a similar stack in GOODS-N using data described in Borys et al. (2003) and Pope et al. (2005). The hatched region marked "Fixsen" is the absolute spectrum of the CIB determined from FIRAS observations on COBE (Fixsen et al. 1998). The hatched region at λ ⩽ 160 μm labeled "Dole" is the background reported by Dole et al. (2006) using a similar stacking analysis of Spitzer data in GOODS-N.
