Rigidity dependence of parallel (λ_∥) and perpendicular (λ_⊥) MFPs of protons (a) and electrons (b) at (1 AU, 90°,0°) for every 10 days from June 1, 2017 to December 31, 2017. Proton MFPs on August 20, 2017 are very close to the December 18, 2017 ones. For identification, we use dash black line to represent proton MFPs on December 18, 2017. Some of them are not shown because they are the same as other days (more details are displayed in Table 2).
