 The following formalism, however, shall not rely on \cref{EDvpHomo},
 but also allow for soft particles for which $\Delta v_\sp(\r)$ is a continuous function of~$\r$.
-\Warn{Currently,
-BornAgain uses the given $v_\sp$
-(given through a particle refractive index)
-in place of the difference $v_\sp - v_\sm(z)$.
-In other words, BornAgain does not subtract the matrix SLD from the particle SLD;
-it leaves it to the user to do this subtraction before entering the particle refractive index.}
 
 The sum~\cref{Evmpr} has the same form as the decomposition~\cref{Edecompose_vz}.
 Nonetheless, implementations are free to choose a convenient mean SLD~$\mv(z)$.
