\caption{{\bf Order 2.}
Cepheid average angular diameters and distances determined through the
application of the modified BW method. The only input is
the diameter variation curve $\Delta D(\phi)$ derived from the integration of the radial
velocity. The distance and average angular diameter are
ajusted simultaneously. The statistical and systematic errors on $d$ are
listed separately in brackets.}
