Raw data

• Selected within p14 era
  • Z->mumu sample (14k)<
  • J/psi->mumu (62k)
  • W->munu (50k).
• Selected within p17 era (from 2002 to february 2006)
  • A p17 sample selected thanks to muo_cert has been added in october 2006 (200k events).
• Selected within p20 era (from august 2006 to october 2006)
  • A p20 sample selected thanks to muo_cert has been added in december 2006 (24k events).

p14 reconstruction

1) Sample of efficient and inefficient Z->mumu events, p14 TMB format. 
Skimmed from the full pass 2 dataset, but not including v13 triggers (runs < 195xxx). 
This is about 50K events, and provides all the data you need to make efficiency plots using muo_cert. 
The selection is described in the Z cross section note, D0note 4689.
/prj_root/1153/muid/z_skim/*/muon_eff_skim.tmb 

2) A larger skim of Z and W events, again p14 TMB format. 
The skim was made from the full pass 2 dataset, but does not include v13 triggers (runs < 195xxx).
Events are selected matching either:
1 medium muon, pT>14 GeV
or
2 loose muons, each pT >14 GeV
The higher of pT or pT corr is used in the cut. 
For CFT only tracks, I recalculated pTcorr using the beam spot.

p17 reconstruction (aka RunIIa)

 
3) OBSOLETE: A p17.06.02  MC pythia sample.  111k
/prj_root/1153/muid/Zmumu_pythia_tmb_p1706fix/TMBfix*
This data set is fixed  and should be compared to p17 fixed data

4) empty slot

5) OBSOLETE: A p17 fixed muo_cert skim in TMB format. (wzreco/muo_cert v04-00-07)
There are ~200000 events, which corresponds roughly to 800 pb-1 of data
/prj_root/1153/muid/muo_cert_skim/p17fixed_p180400_v040007_pre/file_list
The triggers and loose cuts used for this skim are described in the file
/prj_root/1153/muid/muo_cert_skim/p17fixed_p180400_v040007_pre/ZMuFinder.skim
Be aware that using looser cut or additionnal trigger could yield to efficiency biases.
 This skimmed has to be refixed regarding calorimeter isolation and jet content


6) OBSOLETE The data you should no more use (see 8) ):  
Refixed sample made from  sample 5).
200k evts, ~800 pb-1 of data.
/prj_root/1153/muid/muo_cert_skim/p1703_p1804_v040007_refix/file_list

p17.09 data (taken after 24-oct-2005 up to feb-2006)
There are ~30000 events 160 pb-1.
/prj_root/1153/muid/muo_cert_skim/p1709_p180400_v040007_pre/file_list
Produced like sample 5)

7) The MC you should use: 
A p17.09.01 MC pythia sample refixed with p17.09.05. 225k (RequestId 30604)
/prj_root/1153/muid/Zmumu_pythia_tmb_p1709+refix_reqid_30604/TMBfix*
This sample containts only 73k independent event, the rest are duplicate.
Some events are present 19 times !.
See  details  .

8) The data you should use: 
 
Cable swap fixed data. ~250k evts made from all p17 refixed and cable-swap fixed data2MUhighpt skim available in november 2006:
/prj_root/1153/muid/muo_cert_skim/skim_p170903_p170906_v050600_november06/list_files
The inputs files come from the dataset definition:
CSskim-2MUhighpt-PASS3-p17.09.03 
CSskim-2MUhighpt-PASS3-p17.09.06
CSskim-2MUhighpt-PASS3-p17.09.06b

wzreco/muo_cert version v05-00-05 were used using the cuts described in the dedicated RCP: wzreco/rcp/ZMuFinder_skim.rcp 
Be aware that using looser cuts could yield to efficiency biases.
There is no more trigger biases with this version (selection does not rely on trigger).


 p20 reconstruction (Run IIb )
9) 
 Frozen sample for summer 2007 skimmed by muo_cert (TMB format)
  This corresponds to the official p20 pass2 sample for summer 07 analysis and (pre)certification.
There are ~216000 events from p20.08 and p20.07 data.  (~40 000 Zmumu)
From june 9  2006 (run 221703) to April 13  2007 (run 232187)

10) p20.08 p20.07 muo_cert skim of all p20 available data (TMB format).
This correspond to 9) + some data from early run2b + data taken after april 14 2007. 
268 000 events in total from june 9  2006 (run 221703) to June 8 (233491)

The triggers and loose cuts used for skim 9) 10) are described in the file
 wzreco/rcp/ZMuFinder_skim.rcp  of wzreco v06-00-01
Be aware that using looser cuts when analysing the skimmed data could yield to efficiency biases.
