Dipole model analysis of highest precision HERA data, including very low $Q^2$'s

We analyse, within a dipole model, the final, inclusive HERA DIS cross section data in the low $x$ region, using fully correlated errors. We show, that these highest precision data are very well described within the dipole model framework starting from $Q^2$ values of 3.5 GeV${}^2$ to the highest values of $Q^2=$ 250 GeV${}^2$.
