after noticing that the two main data members of TrackerPulse (charge and time) don't have a data field for their respective error I put the issue into the feature request/bug tracker of LCIO (look here).

Two additional things come to my mind:
1) For user-friendliness AND for consistency I asked for two additional members. Is there any reason/belief that somehow a correlation between the two parameters (charge&time) exists, so we have an argument for needing a covariance matrix?

2) For the reconstruction chain further down the processing line it might be needed what the largest single slice inside a pulse is. For now this information is lost and needs to be re-retrieved when needed by looping over the spectrum.
Now I wonder if there is an argument to also call for an additional data member holding this specific information.
