Dear colleagues, I`m not so experienced user and encountered with some problems with curve fitting functions (Genfit works but LeastSquaresFit does not - gives the error that data units are not compatible). Could you help if possible? I`m completely stucked. Thank you.
You are mixing stuff that has units (ko, because you calculate it using built in constants, which have units), and stuff with no units (your data). Therefore PhQfit(vx,Beta_guess) has units, but vy does not. The two must have the same units. Actually, I'm a little surprised that genfit does not complain. Either don't use units at all, or use them consistently. The latter is by far the best option.
