Erratum: Eur. Phy. J. C 10 (1999) 487 (Photon production in relativistic heavy-ion collisions using rates with two-loop calculations from quark matter)

Abstract

It has been shown recently shown that the values of $J_T$ and $J_L$ which appear in Eq.(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.~1--4. The basic result of the paper, that the emissions from the quark matter can outshine those from the hadronic matter when the photon rates upto two-loop level are used, remains valid though the range of $p_T$ over which it happens is reduced to $p_T<$ 0.5, 1, and 2 GeV/$c$ respecitively at SPS, RHIC, and LHC energies.

Comments: Corrected two-loop rates for photon production are used. Five pages, including 4 figures
