Posterior of the SFR parameters. Contours show the 2D posteriors marginalised over all the other 25−2 = 23 parameters. The cyan contours show the constraints from the CIB-KiDS cross-correlation only, the dark blue contours show the constraints from a combination of the cross-correlation and the external SFRD data, and the red contours show the constraints from the external SFRD data only. The dark and light regions in each contour show the 68% and 95% credible regions, respectively. The dashed lines show the best-fit model from M21.
