It turned out that a bug introduced in GModelSpectralNodes::mc() produced that problem. In fact, the case that there is a single node in the MC cache led to an exception instead of using this single node, which is needed for extrapolation. Changing the code as follows solved the problem:
if (m_mc_cum.size() > 1) {
double u = ran.uniform();
for (inx = m_mc_cum.size()-1; inx > 0; --inx) {
if (m_mc_cum[inx-1] <= u) {
break;
}
}
}
else if (m_mc_cum.size() == 0) {
std::string msg = "No valid nodes found for energy interval ["+
emin.print()+","+emax.print()+"]. Either restrict "
"the energy range to the one covered by the "
"spectral nodes or extend the spectral nodes "
"in energy.";
throw GException::invalid_return_value(G_MC, msg);
}
