THE WIENER-FILTERED COBE DMR DATA AND PREDICTIONS FOR THE TENERIFE EXPERIMENT

We apply a Wiener filter to the two-year COBE Differential Microwave R adiometer (DMR) data. The resulting sky map has significantly reduced noise levels compared to the raw data: the most prominent hot and cold spots are significant at the 4 sigma level. Furthermore, the entire c ovariance matrix of the errors in the filtered sky map is known, and i t is therefore possible to make constrained realizations of the microw ave sky with the correct a posteriori probability distribution. The fi ltered DMR sky map is used to make predictions for the Tenerife experi ment. Two prominent features are predicted in a region of the sky not yet analyzed by the Tenerife group. The presence of these features is a robust prediction of the standard cosmological paradigm; if these fe atures are not observed, some of our fundamental assumptions must be i ncorrect.
