Correcting for this changes the Fig.~2. More-over, now the emissions from the quark matter dominate only for $p_T <$ 1 GeV/$c$. The basic result of the paper, that the upper limit of the single-photon production in the WA80 experiment is consistent with the rates for photon production at two-loop level remains valid.Corrected two-loop rates for photon production are used.
