In LoKi functors lesson, one probably can avoid a long paragraph with discussions on VFASPF, there are functors CHI2VX and CHI2VXNDOF that get particle as an argument and evaluate corresponding chi2_VX ( or chi2_VX/ndf).
I think it could simplify a bit the material.
Though, we would like to keep the VFASPF discussion since it's widely used in the stripping lines. Just a brief update on the CHI2VX and CHI2VXNDOF should be useful.
