2PCFs measured from the KiDS-1000 bright sample. The three panels are the auto-correlation w(θ) of the whole sample, and the first and the second tomographic bins, respectively. The blue and pink dots are the measurements corrected by recovered organised random and uniform random. The shaded regions are angular scales corresponding to physical scales smaller than 8h⁻¹Mpc estimated at the mean redshift. The error bars are the standard deviations derived from the covariance matrix provided by the ONECOVARIANCE package. The orange curve is the OR-corrected 2PCF data points measured by Johnston et al. (2021). The black dashed curves in the second and third panels are the best-fit 2PCF from MCMC.
