  • Sigmas now take the azimuth of the momentum at the primary vertex, which should improve kstar resolution (momentum taken before at the decay vertex)
  • Can be switched on and off via a configurable 'kinkPhiAtPv' (default: true)
  • Added a process function to be able to process Kinks and SigmaPlusPCM at the same time, in case it is needed
