Cross-power spectra between WiggleZ galaxies and MeerKAT H I intensity maps at redshift z ≈ 0.4. Maps have been cleaned by a PCA and PCAw analysis with N_fg = 4 (blue circles and orange diamonds respectively) and by mPCA with N_L, N_S = 4, 8 (green squares). We show error bars with 1σ uncertainties and the resulting best-fit curves (solid blue for PCA, dotted orange for PCAw and dashed green for mPCA). The black dashed line is the fitted model from CL23 (same data, different cleaning strategy) that instead was enhanced by a transfer function correction.
