a, b Show the constraint with \({k}_{\max }=0.2\) and 0.5 hMpc−1, respectively. In each panel, the constraints are from the pre-reconstructed power spectrum (\({P}_{{{{{{{{\rm{pre}}}}}}}}}\)) alone (grey dashed line), post-reconstructed power spectrum (Ppost) alone (dark blue dash-dotted line), cross power spectrum between the pre- and post-reconstructed density fields (Pcross) alone (green dotted line), the combination of pre-, post-reconstructed and cross-power spectra (Pall) (red solid line), the combination of pre-reconstructed power spectrum and bispectrum (\({P}_{{{{{{{{\rm{pre}}}}}}}}}+{B}_{{{{{{{{\rm{0}}}}}}}}}\)) (light blue dash-dot-dotted line), the combination of post-reconstructed power spectrum and bispectrum (Ppost + B0) (grey filled region) and the combination of Pall and bispectrum (Pall + B0) (purple solid line).
