Introduction

In this exercise, you will learn how to calculate the luminosity based on a TAG file as input, by running iLumiCalc.exe from the command line.

Running iLumiCalc.exe on an ELSSI file

Clean your environment by starting a new shell or re-starting your current shell.

We will use the requirements file that you created earlier for the tutorial to set up the lcg nightly. Go to your $HOME directory:

cd $HOME

source cmthome/setup.sh -tag=15.6.4,AtlasProduction,32
(Note that you'll get a complaint about directories not existing - don't worry about this - it will only happen once)
echo $TestArea
mkdir $TestArea 
cd $TestArea

Your $TestArea should be 15.6.4.

If things have worked correctly, then you should be able to do

which iLumiCalc.exe

and get something like

 /afs/cern.ch/atlas/software/builds/AtlasEvent/15.6.4/InstallArea/i686-slc4-gcc34-opt/bin/iLumiCalc.exe 

You can then run it for a specific trigger on the ELSSI file as

iLumiCalc.exe -t "L1_MBTS_1_1" -T /afs/cern.ch/atlas/maxidisk/d39/data09/Elisabeth_Vinek_data09_900GeV_physics_MinBias_r988_p62_READ_1265621157_.root | tee log.txt

When it finishes, you should see a final result like
