Good news, everyone.
FastSim now features covariances. Please update your trunk or scrut14 to rev.24408.
A quick example: The KinFitter with the pbarp foumomentum as 4C produces in the example from macro/scrut the following J/Psi mass (red with fit).
Cheers
Ralf

Hi Matthias,
actually the covariances are diagonal in p, theta, and phi, and then transformed to the px, py, pz, E domain. There they are not diagonal anymore.
Best,
Klaus
