Remarks on muons from Ketevi:

   During software and muon weeks in December, we propose a solution 
for the muon ESD and AOD. The implemention was done in 9.4.0, tested and 
debugged recently. Here is what is avaible.

   - For the ESD: CombinedMuon.h, to be used for high Pt and low Pt 
muons (different collections), to handle the association between various 
tracks and also to carry the colorimeter information. The CVS package is 


The builders for the low pt and high pt ESD CombinedMuon, implemented by 
Michela for Muid, are in 


   - For the AOD. The muon AOD has been modified substantially, so as 
to construct the AOD muon from the ESD CombinedMuon, and to add the 
navigation from AOD muon to the ESD CombinedMuon. The CVS package is 


The builder of AOD muon reads in both collections of low and high pt ESD 
CombinedMuon and constructs one collection of AOD, removing the 
ambiguity/overlap between the 2 collections - similarly to was done for 
the electron AOD. This implementation has been done by Stefano. The CVS 
packages are in:


   - There is also a muon isolation tool package in

It can be used for track isolation, at the ESD level or the AOD since the 
TrackParticle collections are available in both data formats. There is 
also an option for calorimeter isolation - this requires the knowledge of 
CaloCell energies within some isolation cone and the energy loss my the 
muon the calorimeter, thus the calo isolation is only available at the ESD 
level on the CombinedMuon.

   - The validation of the muon ESD and AOD is in progress.

   -  We've also added to the ESD and the AOD the TrackRecord 
collection. The TrackRecord gives the MC Truth muon track parameters at 
the muon spectrometer, thus useful for the validation of MOORE.

   - What to expect by 10.0.0: the muon isolation tools mentioned 
above will be used to calculate the calo isolation energies in various 
cones, default = 0.1, 0.2, 0.3, 0.4, 0.4, 0.5, 0.6, and 0.7 and the ESD 
CombinedMuon will filled with this information. During the making of the 
muon AOD, this information is simply copied into the AOD, thus available 
at the analysis level.

   - What we expect in the near future: The equivalent collections of 
CombinedMuon (ESD) and Muon (AOD) for Muonboy/STACO. The muon ESD and AOD 
data classes and the isolation tools are the same for Muid and STACO.
