  We present a preliminary report on the determination of the intercepts and
couplings of the soft pomeron and of the rho/omega and f/a trajectories from
the largest data set available for all total cross sections and real parts of
the hadronic amplitudes. Factorization is reasonably satisfied by the pomeron
couplings, which allows us to make predictions on gamma gamma and gamma p total
cross sections. In addition we show that these data cannot discriminate between
fits based on a simple Regge pomeron-pole and on an asymptotic log^2s-type
behaviour, implying that the effect of unitarisation is negligible. Also we
examine the range of validity in energy of the fit, and the bounds that these
data place on the odderon and on the hard pomeron.
