[Olympus] Radiative effects

[Michael Kohl]

Hi,

there was just a talk at the RADIATIVE2016 workshop by A. Ilyichev on 
"standard radiative effects" including *hard photon emission* and how it 
affects the e+/e- ratios. He can evaluate this for E=2 GeV, too.

Would it be worthwhile to benchmark the MIT Monte Carlo for hard 
bremsstrahlung against it?
What has been the basis of the OLYMPUS implementation without soft-photon 
approximation?

I also just had a brief chat with Peter Blunden, he is offering to provide 
his latest e+/e- ratios (relative to Mo/Tsai or Maximon/Tjon, whatever is 
convenient) as a afunction of epsilon and Q2.
Is there an implementation of "Blunden" in the OLYMPUS simulation, and if 
yes, how old is it?

Best regards
   Michael
