  Charmonium systems in two-flavour QCD at non-zero temperature are studied at,
and above the deconfining transition. Using anisotropic lattices the MEM
approach is used to extract spectral functions for these channels. By carefully
varying some of the irrelevant parameters in the MEM procedure, we confirm that
our systematic effects are under control. The eta_c and J/psi states are found
to persist at temperatures >~ 1.3 T_c in agreement with our previous dynamical
studies.
