7.3.4. Fit parameters and minimizer¶
Change minimiser setup: The default minimiser used is minuit2. See Section 6.2.7.1 for details:
UsineFit @ Config @ Minimiser @ M=0 @ Minuit2 UsineFit @ Config @ Algorithm @ M=0 @ combined UsineFit @ Config @ NMaxCall @ M=0 @ 100000 UsineFit @ Config @ Tolerance @ M=0 @ 1.e-2 ...
TOA CR data to use: data to minimise are picked from the list of data loaded (see Section 6.2.1.1). Their selection (and the errors to use) is detailed in Section 6.2.7.3:
UsineFit @ TOAData @ QtiesExpsEType @ M=0 @ B/C:AMS:KR UsineFit @ TOAData @ ErrType @ M=0 @ kERRCOV:$USINE/inputs/CRDATA_COVARIANCE/ UsineFit @ TOAData @ EminData @ M=0 @ 1.e-5 UsineFit @ TOAData @ EmaxData @ M=0 @ 200. ...
Free and nuisance parameters: The whole business of nuisance and free parameters, as well as the list and syntax of these parameters are given in Section 6.2.7.2:
