CIB bispectrum at 353 GHz in some particular configurations (black points, in Jy3 sr-1). The red curve is the CIB bispectrum predicted from the power spectrum (best-fit model from Sect. 5.5) following Lacasa et al. (2012). The yellow curve is a power-law fit (as given in Table 13). See Sect. 6.5 for more details.
