Comparison of the RSD measurements in FS (red) and CS (blue) with GA on the individual 1000 eBOSS EZmock. FS and CS results are shown on the y-axis, while GA results are on the x-axis. The top row displays the best-fit values for q_∥, q_⊥, and fσ₈, while the bottom row shows their estimated errors σ_q∥, σ_q⊥, and σ_fσ8. The density of points is represented by the color-scale shading, and the dashed lines indicate the line of perfect correlation where the compared parameters are equal. We display the Pearson correlation coefficients between GA and FS, as well as GA and CS. The plus symbols represent the best-fit results from the real eBOSS data as listed in Table 6.
