[b1_ana] b1 at x>=1

[Patricia SOLVIGNON]

Hi all.

Misak Sargsian gave me a code a few years ago to generate his prediction to b1 in the DIS region. I was not sure if we could use it for the QE resin and his reply can be found below. So it is a code for DIS only (and DIS contribution in the x>1 region). 
The relevant littérature for b1 in the QE region is Frankfurt & Strikman, Phys.Rept. 160 (1988) 235-427 (more precisely: section 7 and figure 7.7).
I am going to send an email to Mark Strikman to get the curves from figure 7.7 and maybe more materials.

Patricia
