  We present new lattice results on the continuum extrapolation of the vector
current correlation function. Lattice calculations have been carried out in the
deconfined phase at a temperature of 1.1 Tc, extending our previous results at
1.45 Tc, utilizing quenched non-perturbatively clover-improved Wilson fermions
and light quark masses. A systematic analysis on multiple lattice spacings
allows to perform the continuum limit of the correlation function and to
extract spectral properties in the continuum limit.
  Our current analysis suggests the results for the electrical conductivity are
proportional to the temperature and the thermal dilepton rates in the quark
gluon plasma are comparable for both temperatures. Preliminary results of the
continuum extrapolated correlation function at finite momenta, which relates to
thermal photon rates, are also presented.
