NIKHEF Rome MCatNLO Samples

What are the different samples ?

A short description of the sample necessary for the Rome $t{\bar {t}}$ analysis:

T1: $t{\bar {t}}$ events. Fully hadronic events have been rejected.

T2: $t{\bar {t}}$ events. Fully hadronic events have been rejected and at least one of the tops has a $p_{T}$ greater than 500 GeV/c

A7: (W + 4 jets)-events. The dominant background for the $t{\bar {t}}$ analysis.

Where are the different files located at NIKHEF ?

Log-files

The log-files for most jobs are located in a sub-directory called InputAndLogfiles. Here are some links.
