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 c and J/ states are
found to persist at temperatures 1.3Tc in agreement with our previous dynamical studies.
