Scientific paper

An attempt was made to see if angular dipoles and peculiar velocity data are consistent with cold dark matter model world predictions. The chi-squared statistics were acceptable and the likelihood analysis using these probes of large-scale structure gave normalization parameters which were similar to those determined from considerations of clustering on much smaller scales. The greatest discrepancy was found for the optical dipoles, which gave a normalization about a factor of 2 larger than the canonical choice. Some other indications for more power at large scales were found.
