Generator for Timelike Compton Scattering process.
It includes Bethe-Heitler (BH) process cross section, and The interferenc (between TCS and BH) term cross section
==================== I N S T A L L A T I O N ======================= In the base directory make d directory named lib
mkdir lib
Then make sure you have installed root, It will compile the code using thr $ROOTSYS enviromental variable
Just type make
make
If make is successful, then make sure the lib directory, i.e. pwd/lib is in the $LD_LIBRARY_PATH
To run from an arbitrary location, $TSCGEN_DIR must be set to this repo's directory.

-
Make sure when running, the file CFFs_DD_Feb2012.dat is present in the directory, from where you run the executable. It contains the grid of CFFs, and for interference term cross section calculation, it uses that grid.
-
Also some basic variables are inside the config file named "GenOptions.dat"
- Nsim Number of events to generate
- Eb The beam energy in GeV
- tLim The t_Max value in GeV
- EgMin Photon energy minimum
- EgMax Photon energy maximum
