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 500 GeV

A7: W+4jet events using AlpGen.

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


A short description of the sample necessary for the single-top analysis:

4511: W-gluon single top production using TopReX.

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

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

4540: s-channel single top production using TopReX.

4599: Wbbbar background sample by TopReX. 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).
