We compute temporal correlators and spectral functions for light, open
charm and charmonium mesons in the pseudoscalar and vector channel for
a range of temperatures below and above the deconfinement transition.
The study is carried out using anisotropic lattice QCD with 2+1
dynamical flavours, a_s=0.123fm and a_s/a_t=3.5. The high-temperature
results are benchmarked by comparing them to reconstructed correlators
obtained by direct summation of the zero temperature correlator. We
use two Bayesian methods to reconstruct the spectral functions: the
maximum entropy method and the more recent BR metod.
