Erratum: Eur. Phy. J. C 12 (2000) 109 (A Second Look at Single Photon Production in S+Au Collisions at 200 AcdotGeV and Implications for Quark Hadron Phase Transition)

It has been shown recently that the values of $J_T$ and $J_L$ which appear in Eqs.(2) and (5) of the above paper and which are taken from the work of Aurenche et al are too large by a factor of 4. 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.
