I’m currently running TFractionFitter with 6 MC templates and noticed the fit fractions don’t sum to 1. The fit status is “SUCCESSFUL” and the error matrix is reported accurate. Here’s an example of one my my fit results:
par0 : 0.4912
par1 : 0.484464
par2 : 0.000684191
par3 : 0.000141439
par4 : 0.0231684
par5 : 0.000522719
Sum : 1.00018
Is this a bug? or is there a way I can manually force the sum to always be 1?
