**Comparison of the SDMEs s^{\lambda_{V}\lambda_{V^{\prime}}_{\lambda_{\gamma}\lambda_{\gamma^{\prime}}} obtained from the amplitude method (red circles) and from the SDME method (blue squares). The SDMEs are extracted in the entire kinematic region. The points in the shaded area show SDMEs that can be obtained only if the beam is longitudinally polarized in addition to the transverse target polarization required for all SDMEs here**

**Definition of angles in the process eN -> e\rho^{0}N->e\pi^{+}\pi^{-}N. Here, \PHI is the angle between the \rho^{0} production plane and the lepton scattering plane in the CM system of virtual photon and target nucleon. The variables \theta and \phi are respectively the polar and azimuthal angles of the decay \pi^{+} in the \rho^{0}-meson rest frame, with the z axis being anti-parallel to the outgoing nucleon momentum. The XZ and xz planes both the \gamma^{\star} and \rho^{0} three-momenta**
