Recoil Polarization

Pa, Pb, Pc (in the lab frame, Pc along the electron : default)
P1, P2, P3 (in the scattering plane, P3 along the photon)
Px, Py, Pz (in the reaction plane, Pz along the photon) 
Px', Py', Pz' (in the reaction plane, Pz' along the pion) 
Pt, Pn, Pl (in the reaction plane, Pl along the outgoing nucleon)
