Dear Tetyana,

Regarding your comment “One more point, also addressed already, please remove direct photon T from the figure, they have nothing to do with the true fireball T! You know well that when taking into account radial expansion velocity of the system (which you have to do when you fit pT spectrum!) will bring BOTH phenix and alice results down to ~155 MeV.”

We definitely know about Teff from photons mean here. Actually we have both version “with Teff from photons” and “without from photons”, the figure in our paper we don’t have the effective temperature from photons as you can see from the draft. However, the EM plenary speaker prefer to select the figure with Teff from photons in the figure for his talk as he want to include all the temperature measurements from different EM probes. I don’t think I should tell the speaker which figure to choose, instead I just shared the meaning of the Teff from photons and the advantage of Temperature from thermal di-leptons to the speaker.

Best,

Zaochen
