Hello! I am creating a Geant4 simulation to model how the polarization of light changes as it moves through a column of water, and I am currently implementing Mie scattering into the simulation. I have preliminary values for the the Mie scattering lengths, forward and backward anisotropy and the ratio between forward and backward scattering angles, but I believe the simulation would be more accurate if I could implement custom scattering angle functions as an input as much of the data I’ve obtained from a collaborator is in this format. Does anyone have advice on how I could go about doing this? For context, I am fairly new to to Geant4 and C++, so I’m sorry if what I’m describing is lacking lots of details or if I ask a lot of questions in the replies, but please feel free to ask me to clarify things!
