[Clas12_first_exp] CLAS12 First Experiment Meeting

[Sangbaek Lee]

Hi Volker,

Thank you for the cheerful comments!
I forgot to mention the conclusion in short, parameters are selected for nonradiative DVCS events.
50M events already collected provides statistics similar to the experiment.
450M for inbending, and 500M for outbending will be submitted to the osg after the currently announced issue at the farm is resolved.

I refined plots a little bit and added a short note on radiative corrections.
It might be better to share the full link that shows the latest version.

Best regards,
Sangbaek

Although Maxime may also want to perform more detailed simulations, the demands on simulations to extract the BSA are significantly less compared to what you are dealing with, the extraction of normalized cross sections.
