All-sky distribution of cosmological parameter (Ω_m and H₀) utilizing the Pantheon+ sample combined with the RF method with different screening angles including 30°, 45°, and 60°. Panels (a) and (b) show the results using the RF method with 30°. Panels (c) and (d) are the results of 45°. Panels (e) and (f) are the results of 60°. The proportions of the wrong fitting results are 30.34%, 6.47%, and 0.70% for the screening angles 30°, 45°, and 60°, respectively.
