Double Deeply Virtual Compton Scattering (DDVCS) with the EpIC generator. Currently focusing on the Low-Q2 limit of (Quasi-real) Timelike Compton Scattering.\
The EpIC generator is used to generate DDVCS MC events. Currently there are steering cards for ee and mumu @ 18x275 energy configuration, and ee at 10x130. More configs will come in the future.

Files are output from the generators in hepmc ascii format. These must be afterburned (available in eic-shell), and then converted to hepmc root format (availabe in eic software stack):
abconv -p 0 18x275_ddvcs_edecay_hminus.hepmc ab_18x275_ddvcs_edecay_hminus.hepmc
hepmc3ascii2root ab_18x275_ddvcs_edecay_hminus.hepmc ab_18x275_ddvcs_edecay_hminus.root\
These afterburned hepmc3 root files are currently available at:
/gpfs/mnt/gpfs02/eic/gpenman/
under straightforwardly named directories:
DDVCS_18x275/ DDVCS_muon_18x275/
