Quite!
In case anyone's interested, here are the two relevant papers:
(A measurement of large-scale peculiar velocities of clusters of galaxies: results and cosmological implications.)

(A measurement of large-scale peculiar velocities of clusters of galaxies: technical details)
http://www.nasa.gov/centers/goddard/pdf/276175main_ApJ_inpress.pdf
Garnered from the UT article on the same topic:
(Scientists Detect "Dark Flow:" Matter From Beyond the Visible Universe)
