Input cross-section

The input cross-section used can be found here: /work/halld/home/ijaegle/he4_pi0_primakoff/PRIMEX-D_pi0_he4-corrected-10112021-notree.root

1. all: Primakoff+Coherent+Interference+Incoherent
2. tot: Primakoff+Coherent+Interference
3. prim: Primakoff
4. coh: Coherent
5. interp: positive component of the interference
6. intern: negative component of the interference
7. inc: incoherent quasi-free proton & neutron not distinguish
8. inc_p: incoherent or quasi-free proton
9. inc_n: incoherent or quasi-free neutron

Version 1

Can be found here: /lustre19/expphy/cache/halld/gluex_simulations/PRIMEX/primex_eta_he4-slurm-production-pi0

OBSOLETE

Version 2

Can be found here: /work/halld/home/gxproj2/gluex_simulations/PrimEx-pi0-good-test-24012022

Simulation for:

1. 3 runs
2. From 3GeV to endpoint energy
3. All components and combined
4. Note: interference = N_{interp}^{yield}-N_{intern}^{yield}

WRONG \pi^0 mass set (\pi^\pm used) => OBSOLETE

Version 3

Can be found here: /work/halld/home/gxproj2/gluex_simulations/PrimEx-pi0-good-test-27012022

Simulation for:

1. 3 runs
2. From 3GeV to endpoint energy
3. All components and combined
4. Note: interference = N_{interp}^{yield}-N_{intern}^{yield}
