CRPropa plugin to integrate a magnetic field line.
See the CRPropa plug-in documentation for installation advice.
The FieldLineIntegrator can be used instead of a classical propagation module, e.g., PropagationBP. The positions stored in the cadidate correspond to positions along the magnetic field line, which passes through the source position of the Candidate.
The integration direction - parallel or anti-parallel to the magnetic field direction - can be speciefied with the direction keyword.
When you use the FieldLineIntegrator cite this git repository.
