The Fortran program Opp_eff.f90 solves the vector radiative transfer equation for the coherent component of the reflection matrix;

i.e., the weak localization (opposition) effect in the scattering by a particulate medium is accounted for.

A detailed user manual for the code is available here.

We would highly appreciate informing us of any problems and errors encountered with this program.
