Table 3 The slope b resulting from a fit to the differential cross-section dσ/dt to an exponential form for the reaction γ*p → ρ⁰p, for different Q² intervals. The first column gives the Q² bin, while the second column gives the Q² value at which the differential cross sections are quoted. The first uncertainty is statistical, the second systematic.
