Hi Stefano, hi all,

actually I was hoping that somebody might already have fixed some numbers on the required input precision Wink

As of now, because the mass is not explicitly stored, a Pion for example can (depending on its momentum) have a mass which is wrong by +-2.5MeV when you calculate it from its total energy and momentum.
But I don't have any feeling yet if there might be a situation where this could turn out to be harmful. I'd also be interested in more opinions on the desired precision for the input values.

Best regards,

Marius
