Hi Elisabetta,

The line
RhoCalculationTools::ForceConstantBz(20.0);

tells the analysis framework (Rho) to assume an artificial, constant B-field. Every fitter which needs the B-field (i.e. all vertexers!) will see the constant B_z, if enabled. I would not recommend using it unless you don't have your magnetic field parameter file on hand.


I strongly encourage to use the very same field settings in the whole chain of processing. Which one to pick, Stefono should tell you.

Cheers
Ralf
