1.Ntuple Variables & GEANT files

Location: Most files have been transferred on d02ka (B-project Disk):

/prj_root/786/mub_3/RunIIB/lucotte/
(See the specific directory in Section: 2. Dijet, 3.single electron, ... )

N-tuple definition: overall variables

Variables for the FPS: definition

Variables for the CPS: old & new variables definition

Current area of GEANT files:geant_files

There is a backup of (most of) the GEANT files:

Tape label: FPS_1C

Tape label: FPS_1D

2. Di-jets production

**NEW*: All files have been transferred on d02ka (B-project Disk):
