Hello,
I have been exploring the Vertex class in the LCFIPlus repository, and I am trying to determine how to calculate the number of degrees of freedom (ndf) or retrieve a chi2/ndf ratio from vertex fitting results.
From my analysis, the Vertex class doesn't seem to provide a direct function for this purpose. I was wondering if there is an alternative method in the library to compute ndf for the vertex, or if this calculation needs to be implemented manually based on the constraints and tracks associated with the vertex.
Would you be able to provide guidance on this? If there are related functions in other classes, I'd greatly appreciate it if you could point me in the right direction.
Thank you in advance for your help!
