Reduced chi squared, best-fit growth rate, and corresponding uncertainties resulting from the separate fits of the 25 mocks with spherical full-sky footprint from z = 0.15 to z = 0.25, AP distortion, Planck 2018 cosmology, and the median HOD. Results using the MGP with and without modelling AP distortions are shown in cyan and blue, respectively. The true growth-rate value is shown by a red dotted line.
