Dear author
I would like to know what formula was used to calculate the value of Xmax in the circled part of this picture. If the reference is made to the circled part in the second figure, this calculation result is incorrect.

Dear Sir,

Please note that what is plotted is the total size, not the rms size (see image below) and the rms beam size = sqrt(Exxp_nn*bet). Exxp_nn is the rms unnormalised emittance, the one you are pointing to is the normalised one.
Regards,

Didier
