[clas12_rgk] [EXTERNAL] revised RG-k Train scheme

[Francois-Xavier Girod]

Dear Annalisa

I think it will not take long to double check the reduction factor of the
new wagons on the available 7.5 GeV run
Sorry when I produced the 6.5 GeV number I was just thinking about
validation rather than the full answer to the committee

Best regards
FX
