Annotation	Two-particle correlations of direct photons were measured in central (208Pb+208Pb collisions at 158A GeV. The invariant interferometric radii were extracted for 100<K)(<300 MeV/c and compared to radii extracted from charged pion correlations. The yield of soft direct photons, K)(T)(T)<300 MeV/c, was extracted from the correlation strength and compared to theoretical calculations.
