Have we tested that the QubitFit is doing the same as Zurich ? Because the point of this routine was to test the discrimination the machines were doing. Apart from that and maybe having the plots side to side instead of one in of the other, it looks good. I would love to test on a calibrated qubit.

Thanks looks good to me.
Just a small comment.

Perhaps we could use a better label here.

If you feel like it, I think having two plots one next to the other like the signal and phase ones would look nicer.
