Measured cross-spectra with the best-fit mean emissivity j reconstruction model fit to both the CIB auto- and CIB-lensing cross-spectra (solid coloured), and the best-fit linear bias model (dashed coloured). The χ² values quoted in each panel are the contribution to the global χ² from the data in the panel for the halo model (with N_d.o.f. in brackets), and loosely indicate the goodness of fit (see text for details). The one and two-halo contributions are shown as the dot-dashed and dashed thin black lines, respectively. A light dashed black horizontal line indicates the zero level.
