CIB-galaxy cross-correlations with the five KiDS tomographic bins (rows) and the three CIB maps (columns). The grey points are measured from data, with standard deviation error bars calculated using the square root of the diagonal terms of the covariance matrix. The solid cyan lines show the best-fit cross-correlation signals calculated using the CIB-galaxy cross-correlation measurements alone, while the dashed blue lines show the best-fit cross-correlations when jointly fitting the CIB-galaxy cross-correlation measurements and the external SFRD.
