-To build Starlight:
-
-- First create your build directory (e.g. mkdir <PathToSource>/build)
-- $ cd <BUILDDIR>
-- $ cmake <PathToSource>
-- $ make
-
-This creates an executable file, starlight, in the build directory.
-
-To run starlight a configuration file, slight.in, is needed. Examples of
-this file can be found in the config/ directory.
-
-To run:
-
-$ ./starlight
-
-If you want Pythia support you need to run cmake with an option:
-
-$ cmake <PathToSource> -DENABLE_PYTHIA=ON
-
-In addition the environment variable $PYTHIADIR needs to be pointing
-to the top directory of Pythia8.
-
-P.S. Pythia is disables in this release
-
-//---------------------------------------------------
-
-
-directory standard contains regular Makefile and sample of config file
-
-
-for compilation
-
-1) cd standard
-2) gmake/make
-3) ./starlight

-======= Photonuclear Processes =======
-
-Simulation of photonuclear interactions with STARlight is possible through an interface with DPMJet or Pythia.
-These interfaces can be enabled through options passed to cmake during the configuration process. However, due
-to DPMJet depending on a different version of Pythia from what is used in the Pythia interface, both cannot be
-enabled at the same time.
-
-The gfortran compiler is required to use the photonuclear interfaces.
-
-
- ======= 1. Photonuclear interactions with DPMJet =======
-
-
- ------- 1.1. Obtaining and installing DPMJet -------
-
-
- The DPMJet package can be obtained by contacting the authors as explained here:
- http://sroesler.web.cern.ch/sroesler/dpmjet3.html
-
- Once you have the code proceed with these steps:
-
- Changle the line containing the OPT variable in the DPMJet Makefile:
-
- OPT = -c -C -std=legacy -O -O3 -g -fexpensive-optimizations -funroll-loops -fno-automatic -fbounds-check -v -fPIC
-
- ----- 64-bit -----
-
- You should make sure that all -m32 options are removed from the Makefile.
-
- Unfortunately the DPMJet package depends on a floating point exception trap implementation,
- and only a 32-bit version of that is included in the package. An example implementation can be found here:
-
- http://www.arsc.edu/arsc/support/news/hpcnews/hpcnews376/
-
- Under "Fortran Floating Point Traps for Linux" there is a code example. A file based on this, fpe.c,
- can be found in the external directory in Starlight. Move that to your DPMJet directory and run:
-
- $ gcc -o fpe.o fpe.c
-
- ----- End 64-bit -----
-
- Then in the DPMJet directory run:
-
- $ make
-
- ------- 1.2. Compiling Starlight with DPMJet interface -------
-
- To enable the compilation of the DPMJet interface please follow these steps:
-
- CMake uses an environment variable $DPMJETDIR to locate the DPMJet object files.
-
- $ export DPMJETDIR=<path to dpmjet>
-
- Then create a build directory for Starlight
-
- $ mkdir <build-dir>
-
- and change into it
-
- $ cd <build-dir>
-
- Run CMake with the option to enable DPMJet
-
- $ cmake <path-to-starlight-source> -DENABLE_DPMJET=ON
-
- Then build it
-
- $ make
-
-
- ------- 1.3. Running Starlight with DPMJet interface -------
-
-
- To run Starlight with the DPMJet interface a couple of files are needed in the directory
- where you want to run Starlight.
-
- The files needed are:
- slight.in (Starlight config file. An example suitable for DPMJet can be found in config/slight.in.dpmjet)
- my.input (DPMJet config file. An example can be found in config/my.input)
- dpmjet.dat (Can be found in the DPMJet source directory)
-
- In the slight.in file the relevant production modes (PROD_MODE) for DPMJET is:
-
- 5: A+A single excitation
- 6: A+A double excitation
- 7: p+A single excitation
-
- In addition the minimum and maximum gamma energies must be set. It is important that
- these are within the interval set in the my.input file

-# Description:
-# cmake module for finding ROOT installation
-# requires root-config to be in PATH
-# based on AliRoots's FindROOT.cmake (r41015)
-# in https://alisoft.cern.ch/AliRoot/trunk/cmake/modules
-#
-# following variables are defined:
-# ROOT_CONFIG_EXECUTABLE - path to root-config program
-# ROOTSYS - path to root installation directory
-# ROOT_TARGET - target architecture
-# ROOT_F77 - Fortran complier used building ROOT
-# ROOT_CC - C complier used building ROOT
-# ROOT_CPP - C++ complier used building ROOT
-# ROOT_VERSION - ROOT version
-# ROOT_SVN_REVISION - ROOT subversion revision
-# ROOT_BIN_DIR - ROOT executable directory
-# ROOT_INCLUDE_DIR - ROOT header directory
-# ROOT_LIBRARY_DIR - ROOT library directory
-# ROOT_LIBRARIES - linker flags for ROOT libraries
-# ROOT_AUX_LIBRARIES - linker flags for auxiliary libraries
-# ROOTCINT_EXECUTABLE - path to rootcint program
-# ROOT_MAJOR_VERSION - ROOT major version
-# ROOT_MINOR_VERSION - ROOT minor version
-# ROOT_PATCH_VERSION - ROOT patch level
-# ROOT_LIBS - list of ROOT library files
-#
-# Example usage:
-# find_package(ROOT 5.26 REQUIRED Minuit2)
-#
-#
-# The module also provides a function to generate ROOT dictionaries.
-# Example usage:
-# set(ROOTPWA_DICTIONARY ${CMAKE_CURRENT_BINARY_DIR}/someDict.cc) # set dictionary path
-# root_generate_dictionary(
-# "${ROOTPWA_DICTIONARY}" # path to dictionary to generate
-# "${INCLUDE_DIR1};${INCLUDE_DIR2}" # list of includes
-# "class1.h;class2.h;class3.h" # list of classes to process
-# "someLinkDef.h" # ROOT linkDef file
-# )
-# set(SOURCES ${SOURCES} ${ROOTPWA_DICTIONARY}) # append dictionary to sources

-// Description:
-// calculates n-body phase space (constant matrix element) using various algorithms
-//
-// the n-body decay is split up into (n - 2) successive 2-body decays
-// each 2-body decay is considered in its own center-of-mass frame thereby
-// separating the mass from the (trivial) angular dependence
-//
-// the event is boosted into the same frame in which the n-body system is
-// given
-//
-// based on:
-// GENBOD (CERNLIB W515), see F. James, "Monte Carlo Phase Space", CERN 68-15 (1968)
-// NUPHAZ, see M. M. Block, "Monte Carlo phase space evaluation", Comp. Phys. Commun. 69, 459 (1992)
-// S. U. Chung, "Spin Formalism", CERN Yellow Report
-// S. U. Chung et. al., "Diffractive Dissociation for COMPASS"
-//
-// index convention:
-// - all vectors have the same size (= number of decay daughters)
-// - index i corresponds to the respective value in the (i + 1)-body system: effective mass M, break-up momentum, angles
-// - thus some vector elements are not used like breakupMom[0], theta[0], phi[0], ...
-// this overhead is negligible compared to the ease of notation
-//
-// the following graph illustrates how the n-body decay is decomposed into a sequence of two-body decays
-//
-// n-body ... 3-body 2-body single daughter
-//
-// m[n - 1] m[2] m[1]
-// ^ ^ ^
-// | | |
-// | | |
-// M[n - 1] --> ... --> M[2] --> M[1] --> M [0] = m[0]
-// theta[n - 1] ... theta[2] theta[1] theta[0] = 0 (not used)
-// phi [n - 1] ... phi [2] phi [1] phi [0] = 0 (not used)
-// mSum [n - 1] ... mSum [2] mSum [1] mSum [0] = m[0]
-// = sum_0^(n - 1) m[i] = m[2] + m[1] + m[0] = m[1] + m[0]
-// breakUpMom[n - 1] ... breakUpMom[2] breakUpMom[1] breakUpMom[0] = 0 (not used)
-// = q(M[n - 1], m[n - 1], M[n - 2]) = q(M[2], m[2], M[1]) = q(M[1], m[1], m[0])

-// Description:
-// Nystrand 220710
-// Fixed bug which gave incorrect minv distribution in gammagammaleptonpair.
-// Moved loop over W and Y from pickw to twoLeptonCrossSection in
-// gammagammaleptonpair to speed up event generation.
-// Changed to Woods-Saxon radius in twophotonluminosity to be consistent
-// with old starligt.
