Integrated flux density at λ = 1.1 mm and λ = 1.3 mm. The right axis shows the fraction of resolved CIB. The yellow shaded region is the CIB measured by COBE (Puget et al. 1996; Fixsen et al. 1998). The blue symbols are the results from this work (we used the differential number counts by Scott et al. (2012), indicated by green symbols for S> 1 mJy). The blue crosses with dashed error bars are the results from this work, corrected for the flux boosting, using Eq. (4) in Hogg & Turner (1998). The orange symbols are from the number counts estimated by Hatsukade et al. (2013). The red, green, cyan, and black solid curves are the model predictions by Cai et al. (2013), Hayward et al. (2013), Shimizu et al. (2012), and Béthermin et al. (2012), respectively. The blue dashed curve shows the integrated flux densities estimated from the best-fit Schechter function, and the blue shaded region indicates its statistical uncertainty.
