The cosmic infrared background history since z ~ 2 at 24, 70, 100, and 160 μm as measured from galaxies selected at 24 μm with S₂₄ > 80   μJy. The 24 μm data come from Le Floc’h et al. (2009), and the 70 and 160 μm data from this work, all using the Spitzer/MIPS data of COSMOS field. The 100 and 160 μm data in four redshift bins are from Berta et al. (2010) in GOODS-N with Herschel/PACS (using the same 24 μm prior.).
