The Q² dependence of the cross section for exclusive ρ⁰ electroproduction, at a γ*p centre-of-mass energy W = 90 GeV. The ZEUS 1994 [53] and the ZEUS 1995 [10] data points have been extrapolated to W = 90 GeV using the parameterisations reported in the respective publications. The inner error bars indicate the statistical uncertainty, the outer error bars represent the statistical and systematic uncertainty added in quadrature.
