[Gate-users] MU and bad_alloc

[catarina veiga]

Thanks for the answer. It was very useful.
>From what I see on the .cc you have a function that reads the beam MU and
energy and converts to number of protons. Can you indicate me any reference
to the equation used, like any article were I can find information of it?
Kind regards,
Catarina Veiga
