this point is the origing of the branch earth_cutoff_rigidity_mode. The branch contains the 2020 model of rigidity cutoff. The current model has issues, so the old model is takes instead. The plan is to adapt the code in this branch to the current core.

The version of AMPS from  Apr 8 11:20:59 2020 (commit d6d7854db44b8e6c63306d8d3e514accbc5ed7c3) seems to be used in calculating of the rigidity cutoff for the 2021 AMPS paper

Added: the capability of controlling the SEP model with the SWMF's PARAM.in. The AMPS' test case that uses that is test_SEP-SC-IH--FL--FL-attachment--Droge_diffusion. The test uses PARAM.in from SWMF_data/PT/AMPS/data/input/SEP/SC-IH--FL--PT (SWMF_data's commit a51cfd932bc3cf53e1af7fcc2e5722c8541968af)

PIC::ParticleSplitting::Split::Scatter(), particle deleting algorithm: a search through the lists is implemented in 10549d7a8fb067cf51525c0f2c205dae3210dc17, a tree-type data structure is implemented in 9d8474c9be04f21769addae940720beb20686783. It seems that both are working fine.

SEPs along magnetic field lines (input: sep_focused_transport-ih--fl-droge__diffusion__simple_injection.input)
GCRs injected from the boundary of the domain (input: sep_focused_transport-ih-mover_he_2019_ajl_drift-box.input)

As a component of the SWMF, AMPS model SEPs moving along a set of magnetic field lines (input file: sep_focused_transport-ih--fl-droge__diffusion__simple_injection.input)
