Experiment: CAA Run E1C, 2003

Spokespersons: M. Osipenko, G. Ricco

Experiment comment: The date were obtained from a comined analysis of five different beam energy settings: 1.5, 2.5, 4.0 and 4.4 GeV. The final structure functions are corrected for bin size effect and therefore correspond to an infinitely narrow bins.
