Query: PSCz-1.2 Jy Comparison: A Spherical Harmonics Approach   We perform a detailed comparison of the IRAS PSCz and 1.2-Jy spherical
harmonic coefficients of the density and velocity fields in redshift space. The
monopole terms predicted from the two surveys show some differences. The
mismatch between the velocity monopoles arises from faint sources and
disappears when extracting a PSCz subsample of galaxies with fluxes larger than
1.2 Jy. The analysis of PSCz dipole moments confirms the same inconsistencies
found by Davis, Nusser and Willick (1996) between the IRAS 1.2-Jy gravity field
and MARK III peculiar velocities. We conclude that shot-noise, which is greatly
reduced in our PSCz gravity field, cannot be responsible for the observed
mismatch.
