Query: The proton structure function and a soft Regge Dipole Pomeron: a test
  with recent data   A recently published soft Regge Dipole Pomeron model intended for all $x$ and
$Q^2$ is proved to give a good agreement with (non fitted) recent HERA data
from ZEUS (SVX95) on the protonstructure function $F_2^p(x,Q^2)$ at low $Q^2$
and low $x$. The model also reproduces (without fit) the recently estimated
experimental derivatives ${\partial F_2^p\over\partial\ell n Q^2}$ and
${\partial \ell n F_2^p\over\partial\ell n (1/x)}$ in a wide $x$ and
$Q^2$-region.
