Hi,
I have been using esfit in Easyspin 6.
I have been simulating a system with 2 spins and noticed that the stdev value for the weight parameter sometimes gives values a hundred fold higher than the best values calculated. I think it is a bug as it tend to happen if I start the simulation with values from 0-1, but if I use starting weight values lets say around 50 the stdev is reasonable. As an interesting point, regardless of the starting point, I am getting the same fitting if we transform the values to percentage, just really different stdev values.
thanks
Juan Carlos.
