Hi,

Regarding item 3 of these minutes, I would like to clarify what the "1 to 1 relationship" for raw calorimeter hits implies.

Some excerpts from the minutes follow:

> 3) Link between Hits and raw Hits
> a) TrackerHit->TPCHit: need 1 to many relation, cannot
> use LcRelation, because of different types (VTXHit,SITHit,...)
> b) CalorimeterHit->RawHit - need only 1 to 1 relation, could
> in principle use LCRelation - but should be consistent
> with TrackerHit


> 3)
> ...
> proposal is that CalHit.getRawHit() returns a single LCObject
> TrackerHit.getRawHits() returns a vector of LCObjects.


Does this mean that a LCRelation keeps track of one and only one RawCalorimeterHit associated with a SimCalorimeterHit? If so, this design does not allow the implementation of crosstalks for adjacent cells. Can we change this design? We were planning to implement crosstalk in our digitization software.

Thanks,
Guilherme
