The different samples

A short description of the sample necessary for the Rome tt analysis:

T1: TTbar events using MCatNLO. Fully hadronic events were rejected.

T2: TTbar events using MCatNLO. Fully hadronic events were rejected and at least 1 top has $p_{T}>$ 500 GeV

A7: W+4jet events using AlpGen.

Note 1: Given the limited manpower and diskspace we only collected a subset of all file formats (no 'simul' and ESD files for example).

Note 2: In producing the TopNtuples for the A7 sample some AODs were discarded since they gave problems. The TopNtuples have a bit less events than the AODs.

A short description of the sample generated using TopReX. All sample were reconstructed with Full Simulation (GEANT4) unless specified.

4511: W-gluon single top production.

4520: ttbar pair production. W- decays to leptons (e, mu), W+ decays to jets

4521: ttbar pair production. W+ decays to leptons (e, mu), W- decays to jets

4522: ttbar pair production. Dilepton sample.

4530: W-top associated production. W+ decaying to hadrons, W- decaying to leptons.

4531: W-top associated production. W- decaying to hadrons, W+ decaying to leptons.

4540: s-channel single top production.

4599: Wbbbar background sample. ATLFAST ONLY.

T1 sample

Sample	Sub-sample	Location	Statistics
MatrixElement files		Repository	200 x 12,500 events
Generator POOL files		Repository	200 x 5,000 events
CBNT	Rome	Repository	7,000 x 50 events (1000 files missing)
AOD	AtlFast	Repository	200 x 5,000 events
	Full (Rome)	Repository	4,000 x 50 events
	Full (Rome/Eric)	Repository	7,000 x 50 events (few still missing)
TopNtuple	AtlFast (V6)	Repository	20 x ?? events
	Full (Rome/Eric) (V6)	Repository	14 x ?? events

How to get the Ntuples to your institute:

To copy all TopNtuples from NIKHEF to your institute just get the following small python script called Get_TopNtuples_From_NIKHEF.py and run it: ./Get_TopNtuples_From_NIKHEF.py. Note that for the AOD's you will have to do a bit more sophisticated and get a list of ascii files first (more later).
