Latitudinal Dependence of Cosmic Rays Modulation at 1 AU and Interplanetary Magnetic Field Polar Correction

Table 4

Percentages of North-South asymmetry of proton intensities (Δ_N-S) as a function of the kinetic energy, using three values for the extension of the polar regions.

Energy range	ΔN-S (%)
	𝜃20^∘	𝜃25^∘	𝜃30^∘
0.35–0.98 GeV	−8^+6−6	−11^+5−4	−13^+4−4
0.76–2.09 GeV	−5^+5−6	−6^+5−5	−9^+3−3
2.09–200 GeV	−1^+3−1	−3^+3−3	−4^+2−2
