When generating MC using the MCWrapper web form, the default energy range is 3.0 to 11.6 GeV. By default, MCWrapper should take this beam energy range and rescale things by the flux in ccdb. For Spring 23, we only have tagged photons down to about 7.8 GeV:
Instead of properly generating according to this measured flux, I find that there are generated beam energies all the way from 3.0 GeV up to 11.6 GeV:
Alex found that adding the line
define beamconfig beam.config
to the generator config file fixes the issue, but this is not done by default in MCWrapper.
