Power spectra and derived foreground components after GPR analysis of the coherently averaged combined data: spherically averaged power spectra (left-hand panel), delay spectra averaged over all baselines (middle panel). The right-hand panel shows the variance of the different foreground components across frequency. The shaded area highlights the uncertainty (2σ) from the GP process (equation 9) and the uncertainty on the model fit from the MCMC run on to the foreground power spectrum components.
