id summary reporter owner description type status priority milestone component version resolution keywords cc 18 Find out if there is a biais introduced by improving the onshell-ness of the input momenta Daniel somebody when we get a momentum configuration we first 'improve it' to make sure all momenta are as much on-shell as possible, while conserving momentum. I am wondering if that could introduce a bias, for example it could be that the momentum reshuffling is taking initial momenta out of the beam axis. I don't think it is an issue, but we also have to decide if we want it to be mentioned in the paper task new minor component1
