Hello Albrecht,

Thanks for finding that. I want to make two remarks. First, the PndKinVtxfitter is not the "final product" as everybody wants it to be. As discussed with Jim, the developer will hopefully be invited for a period to finalize it. Second, the fitter is using always a list of true reconstruction tracks, not intermediate composite particles. Hence it tries to fit your K+K-pi+ to one vertex.

Greetings.
Ralf
