Query: Aspects of model dependence of eta'-eta complex treated by going beyond
  the isospin limit   Exploring the extent of model dependence, we study effects of certain
Ansaetze for the T-dependence of the correction term in the QCD topological
susceptibility. The one producing unwanted effects on results at T > 0 in the
eta'-eta complex in the usual limit of isospin symmetry, is largely cured from
its peculiar behavior and brought into agreement with the other, when breaking
of isospin symmetry is allowed and the realistic quark mass ratio m_u/m_d =
0.50 is adopted.
