def15085 18Revision 1.70 2002/05/10 22:28:30 nilsen
19Changes by Massimo Masera to allow the TTree of clusters to be written to a
20file otherthan the one with digits in it.
21
ed9afcd2 22Revision 1.69 2002/05/05 21:06:55 nilsen
23Added GetSimulationMoel, and fixed up SetDefaultSimulation to do the
24proper initilization when a simulation has already been defined.

54b8cf3b 26Revision 1.68 2002/05/02 18:51:53 nilsen
27AliITS.h
28 Method MakeBranchR has now a second argument, with a default value:
29 Option_t *opt=" ". Opt="Fast" is to create a separate branch
30 for fast points in TreeR
31 New method MakeBranchRF: it a separate branch in TreeR for Fast Points
32
33AliITS.cxx
341) TTree->Write() replaced with TTree->AutoSave for TreeS, TreeD and
35 TreeR
362) Changes in MakeBranchR to allow the creation of a special branch
37 for fast points

45
aa044888 46Revision 1.65 2001/11/27 16:27:28 nilsen
47Adding AliITSDigitizer class to do merging and digitization . Based on the
48TTask method. AliITSDigitizer class added to the Makefile and ITSLinkDef.h
49file. The following files required minor changes. AliITS, added functions
50SetHitsAddressBranch, MakeBranchInTreeD and modified MakeBranchD.
51AliITSsimulationSDD.cxx needed a Tree indepenent way of returning back to
52the original Root Directory in function Compress1D. Now it uses gDirectory.
