Recoil Polarization


P P P3 (in the scattering plane, P3 along the photon : default)
P P Pz (in the reaction plane, Pz along the photon) 
Px' Py' Pz' (in the reaction plane, Pz' along the pion) 
P P Pl (in the reaction plane, Pl along the outgoing nucleon)
(see further details on coordinate frames)
