Peculiar velocity dipoles of field galaxies

The Tully-Fisher (TF) relation is applied to obtain peculiar Velocities of held spiral galaxies and to calculate dipoles of the peculiar velocity fiel d to cz similar or equal to 8000 km s(-1). The field galaxy sample is spati ally coextensive with and completely independent of a cluster sample, for w hich dipole characteristics are given in a separate paper. Dipoles of the p eculiar velocity field are obtained separately by applying (1) an inverse V ersion of the TF relation and selecting galaxies by redshift windowing and (2) a direct TF relation, with Velocities corrected for the inhomogeneous M almquist bias and windowing galaxies by TF distance. The two determinations agree, as they do with the cluster sample. When measured in a reference fr ame in which the Local Group is at rest, the dipole moment of field galaxie s farther than similar to 4000 km s(-1) is in substantial agreement, both i n amplitude and direction, with that exhibited by the cosmic microwave back ground radiation field.
