[Clas12_rgb] concerning figure 5 of nDVCS paper draft, VGG predictions compared with our data

[ajhobart]

Dear Valery, RGB,

following our discussion during the last RGB meeting concerning figure 5 
of the nDVCS paper draft, we have performed a scan using VGG of 
different values of Ju and Jd and evaluating for each set a chi2 with 
the 9 data points that we extract with our analysis. Indeed, this scan 
has shown that there are other values of Ju and Jd that are more 
"preferred" by our extracted harmonics than the ones we had initially 
put in the paper. We have updated figure 5 accordingly (I attach it here 
also).

color code for figure 5

     //   ju       jd      reduced chi2
     //-0.45    0.2  3.03423                blue
     //-0.25    0.15 3.19268               black
     //-0.2      0.15 3.1004                 Red

Attached also you will find the plot with Ju, Jd and chi2 value for each 
set as you requested. It seems that there is a particular preferred 
range for Jd (around 0.15) but none for Ju.


thanks

Best regards

Adam
