By measuring these velocities, we have a unique opportunity to test the cosmological model at the lowest redshifts. We perform this test, using current data to constrain the amplitude of the \"signal\" covariance matrix describing the velocities and their correlations. We consider a new, well-calibrated \"Supercal\" set of low-redshift SNe Ia as well as a set of distances derived from the fundamental plane relation of 6dFGS galaxies.
