 where $Z_{l}^{m}(\Omega,\Phi)=Y_{l}^{m}(\Omega)e^{-i\Phi}$ is a phase-rotated spherical harmonic, $\Omega$ is the solid angle, $\Phi$ is the angle between the production and polarization planes, $P_{\gamma}$ is the polarization magnitude, $[l]$ are the partial wave amplitudes, $m$ is the associated m-projection, $k$ refers to a spin flip ($k=1$) or non-flip ($k=0$) at the nucleon vertex, and $\kappa$ is an overall phase space factor.
 
+The details for this model have been worked out in [10.1103/PhysRevD.100.054017](https://doi.org/10.1103/PhysRevD.100.054017) (2019).

 The amplitude model is implemented in [AmpTools](https://github.com/mashephe/AmpTools) and symbolically in Python using [SymPy](https://docs.sympy.org) with additional tools from [`amptools`](https://ampform.rtfd.io) ([ComPWA Project](https://compwa.github.io)). Dynamics are not yet included (model-indepedent by binning over energy). So we are just comparing linar combinations of spherical harmonics, but the comparison can be extended by investigating final states with a vector meson and/or parametrizing dynamic lineshapes.
