The available distances of galaxies are combined to produce a unified view of galaxy motions within the so-called great attractor (GA) region. The data base includes 253 galaxies within 40 deg of the nominal GA center. Spirals and ellipticals are grouped into clusters to reduce Malmquist bias. Checks are made for systematic errors in the motions of ellipticals that are correlated with cluster richness, structural parameters of the galaxies, or errors in Galactic absorption, and no significant effects on the observed large-scale motions are found. Other evidence strongly supporting the current distance indicators is reviewed, and arguments are presented in favor of the cosmic background radiation defining the correct velocity rest frame. The basic conclusion of the study is the affirmation of the fundamental correctness of the present body of measured galaxy motions.
