Add an overload for Pandora for the member function propagateToLayer#42
Merged
Conversation
This overload is used by Pandora for propagating tracks without fitting. There exists another overload that takes an EDM4hep hit and we could pass the last hit that was added to the track to it. However, that doesn't work because that overload will try to get the TKalTrackSite (track measurement) that is only built after fitting, which Pandora does not need since it uses the refitted tracks (for CLD).
