Target Polarization

P1, P2, P3 (in the scattering plane, P3 along the photon : default)
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)
h electron polarization (helicity)
