Dependencies

• ROOT 6.06.02
• My 'common' libraries: https://github.com/abmorris/common
  • Included as a git submodule for this project. After cloning, you must do git submodule init then git submodule update
  • Remember to do git submodule update after each git pull
• My fork of RapidFit: https://github.com/abmorris/RapidFit
  • Use the branch bsphikk
  • scripts/angacc.sh and fits/runall.sh assume that RapidFit/bin/fitting is in $PATH

Getting the nTuples

For the collision data and full MC ntuples, it should be enough to run ganga Ganga-DaVinci.py from the folder gridjobs/DaVinci/AllnTuples/
For the generator-level MC, see gridjobs/Gauss/PhaseSpaceMC/Ganga-Gauss.py
The file scripts/getoutputdata.sh relies on there being a file called LFNs.txt in each job directory

Running the selection

Should be as simple as running scripts/ANALYSIS.sh from the line containing merge.sh downwards

Acceptance

The output files of scripts/angacc.sh and scripts/angacc_hist.sh should be pointed to by fits/modules/pdf/moments_acceptance.xml and fits/modules/pdf/histogram_acceptance.xml respectively

Angular fit

The script fits/runall.sh will assemble the RapidFit XML files and perform fits. It can take arguments to specify which fits should be run. See fits/README.md for more details. There are also scripts to run on the Edinburgh batch systems (SOPA and Eddie).
