19 : ///
20 : /// Special implementation of AliMUONVClusterServer, which will only return
21 : /// clusters from a pre-defined cluster store.
22 : ///
23 : /// Made to recover the old (i.e. before introduction of VClusterServer) behavior
24 : /// of the MUON recontruction where rec points were always written to TreeR,
25 : /// and then the tracking picked them from that tree, in order to have the
26 : /// possibility to save full rec points (for debugging the spectro, mainly, should
27 : /// not be an option used during final production).
