On the magnetic cycle in the GCR intensity On the magnetic cycle in the GCR intensity in the inner and outer heliospherein the inner and outer heliosphere

Topics:

Near the Earth for H, T≈200 MeV: Jmax(A<0) ≈ 0.8 Jmax(A<0)

Beyond the TS: Jmax(A<0) ≈ 4 Jmax(A<0)? It looks so.

Topics:It is believed that 2D TPE only simulates CS-effects. To study

them properly one needs 3D TPE.We derive the exact 2D TPE for the intensity averaged over the

longitude from the 3D one. It could be used to estimate the errors of the simulation.

We derive the expressions for the averaged over the longitude drift velocities (for any CS-surface and for the Tilted CS model) and compare them with the known ones.
