[Halld-physics] plot of rho omega phi

[Alexander Austregesilo]

Hi Elton,

I made a simple parametrization of the Laget curve for rho 
photoproduction and put it into a plot with our cross sections for low 
and high energy as a function of W (see attachment). The shape seems to 
agree quite well, but our absolute value is lower at the high energy 
end. This could be explained by the too shallow t slope in MC, which 
overestimates our acceptance.

Best regards,

Alex
