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

Table 8

Average (in percentage, %), for BESS-1999, BESS-2000, and BESS-2002 obtained from (17) without enhancement of the diffusion tensor along the polar direction ( ), , , and using “R” and “L” models for the tilt angle and No Drift approximation. The differential intensities were calculated accounting for particles inside the heliospheric regions for which solar latitudes are lower than .
