COSMIC MICROWAVE BACKGROUND ANISOTROPIES FROM SCALING SEEDS - FIT TO OBSERVATIONAL DATA

We compute cosmic microwave background angular power spectra for scali ng seed models of structure formation. A generic parametrization of th e energy momentum tensor of the seeds is employed. We concentrate on t wo regions of parameter space inspired by global topological defects: O(4) texture models and the large-N limit of O(N) models. We use chi(2 ) fitting to compare these models to recent flat-band power measuremen ts of the cosmic microwave background. Only scalar perturbations are c onsidered. [S0031-9007(97)04954-5].
