Abstract:
We have measured the velocity of the Local Group with respect to an
inertial frame defined by the 119 Abell and Abell, Corwin, & Olowin
(ACO, Cat. VII/110A) clusters contained within 15000km/s. The
observations consist of a full-sky peculiar velocity survey with an
effective depth ranging from 8000 to 11000km/s, depending on how the
observations are weighted with redshift. This is the deepest peculiar
velocity survey yet conducted. Clusters are selected by heliocentric
redshift, and the sample is volume-limited. We use the Hoessel
(1980ApJ...241..493H 1980ApJ...241..493H) relationship between the metric luminosities of
the brightest clusters galaxies (BCGs) and the slope of their
brightness profiles as the distance indicator. The Cousins R-band
luminosity within a metric radius of 10h-1kpc yields a typical
distance error of 16% for a single BCG.

Note (1): The alpha parameter is the log slope of the SB profile at 10h-1kpc.
alpha is proportional to d(logLm)/d(log(r|rm)) (Hoessel,
1980ApJ...241..493H 1980ApJ...241..493H), where Lm is the absolute magnitude measured in
apertures of fixed metric size, rm.
