Galaxy clustering: the projected galaxy clustering signal of the six stellar mass bins in the KiDS-Bright galaxy sample defined in Table 1. The solid lines represent the best fitting fiducial halo model (Sect. 2.3, Eq. (27)) as obtained using an MCMC fit, with the 68 percent confidence interval indicated with a shaded region. We caution that the quality of the fit cannot be judged by eye, because of the covariance in the data, between the observed bins and between the observables. The reduced χ² value for this observable is 1.42 (d.o.f. = 71.62, p-value = 0.01), estimated using the method presented in Appendix C.
