  We present a new energy-dependent partial-wave analysis of all
antiproton-proton elastic and charge-exchange scattering data below 925 MeV/c
antiproton laboratory momentum. The long-range parts of the chiral one- and
two-pion exchange interactions are included exactly. The short-range
interactions, including the coupling to the mesonic annihilation channels, are
parametrized by a complex boundary condition at a radius of r=1.2 fm. The
updated database, which includes significantly more high-quality
charge-exchange data, contains 3749 scattering data. The fit results in
chi^2_min/N_df=1.048, where N_df=3578 is the number of degrees of freedom. We
discuss the description of the experimental data and we present the
antiproton-proton phase-shift parameters.
