Abstract:

This note describes, schematically, the improvements applied to the measurement of $F_2^{ep}$ with the '95 Shifted Vertex Data. The kinematical region of the measurement is now extended up in $Q^2$ ( up to $Q^2=17$ GeV$^2$) and the available number of events is increased. In addition, they allow to give a correct estimation of the background and a better understanding of the data.
