People who write RawTrackerHit creators must be reminded to sum contributions before digitization. There is no support for this is in the class system we have specfied so they will need to do it themselves.
Clusters
- There are two cluster options on the table. A class like Rob's or Rich's stripped down version. Something like Dima suggested. We have not yet made a decsion on this.
- We will add some organized container of clusters to the event. Perhaps along the model Rob suggested, perhaps a different one. If we go with 1b), the container will hold ClusterData.
- If we go with 1b), should we also add a parallel container of TrackCluster objects instantiated with a null helix?
- There are no plans to persist clusters.
- We do not have a solution to bookkeeping which hits remain available for subsequent pattern recognition. What ever solution we choose, it will not modify clusters that are already in the event.
