CRPropa 3.2

CRPropa 3.2

Bug fixes:

• Fix of reflective boundary condition for scalar- and vectorgrids
  that showed asymmetry and discontinuities (See issue [#361]).
• Fix in EMTripletPairProduction
• Fix of the data files of the Hackstein EGMF models as well as the
  corresponding example notebook.
• Fix of axis normalization of getRotated in Vector3.h.
• Fix of secondary spectra in electromagnetic interactions
  (EM*-modules), issue [#334] and pull request [#15] in crpropa-data.
• Fix weight inheritance for secondary particles; they are created with
  their parents weights as initial weights now.

New features:

• Add modules for first and second order Fermi acceleration
• Make custom photon fields available in the PhotoPionProduction module.
• Add tricubic- and nearest neighbour interpolation routines for scalar-
  and vectorgrids.
• Add the new PolarizedSingleModeMagneticField class for polarized/
  helical single mode magnetic field models.
• Add a source feature for targeted emission, following the
  von-Mises-Fisher distribution
• Updates in SNR and pulsar source distributions

Interface changes:

• Plane wave and grid turbulence models use same parameter convention now

Features that are deprecated and will be removed after this release

• External extensions DINT and Eleca, which can be replaced with the
  EM*-modules combined with the thinning option for reasonable computation
  times.

New plugins and resources linked on the webpages:

• Updated version of the CLUES EGMF models
