  The relevant gamma energy range is explicitly identified where additional
gamma$ strength has to be located for having an impact on astrophysically
relevant reactions. It is shown that folding the energy dependences of the
transmission coefficients and the level density leads to maximal contributions
for gamma energies of 2<=E_gamma<=4 MeV unless quantum selection rules allow
isolated states to contribute. Under this condition, electric dipole
transitions dominate. These findings allow to more accurately judge the
relevance of modifications of the \gamma strength for astrophysics.
