  We present a comparison between the peculiar velocity field measured from the
ENEAR all-sky $D_n-\sigma$ catalog and that derived from the galaxy
distribution of the IRAS PSCz redshift survey. The analysis is based on a modal
expansion of these data in redshift space by means of spherical harmonics and
Bessel functions. The effective smoothing scale of the expansion is almost
linear with redshift reaching 1500km/s at 3000km/s. The general flow patterns
in the filtered ENEAR and PSCz velocity fields agree well within 6000km/s,
assuming a linear biasing relation between the mass and the PSCz galaxies. The
comparison allows us to determine the parameter $\beta=\Omega^{0.6}/b$, where
$\Omega$ is the cosmological density parameter and $b$ is the linear biasing
factor. A likelihood analysis of the ENEAR and PSCz modes yields $\beta=0.5 +-
0.1$, in good agreement with values obtained from Tully-Fisher surveys.
