CombineParticles: vertexfitters property has an effect
so, apparently CombineParticles
' inherited m_vertexFitNames
property has no effect whatsoever on the algorithm, according to the first warning in initialize()
.
It tells me to configure ParticleCombiners
rather than VertexFitters
. So i did, and i found the opposite behaviour. changing the default in VertexFitters
seemed to have an effect (on the algorithm speed), but doing the same change on ParticleCombiners
instead did nothing whatsoever to the throughput.
Whats going on there? Why is VertexFitters not supposed to change anything?
