In the top panel, the filled blue squares show the estimated growth rate, fσ₈, as a function of the cut-off wave number, k_max^p, of the momentum power spectrum. We fixed k_max = 0.3 h Mpc⁻¹ for the density and cross power spectrum. They were derived from the BGS and DESI-PV survey data. The dashed magenta line indicates the average of the filled blue squares. The dashed yellow line indicates the fiducial value fσ₈ = 0.466 of mocks. The bottom panel illustrates the reduced χ² values for each measurement, depicted by filled green circles.
