Abstract
In this work we present a partially new method to analyze fluctuations which are induced by causal scaling seeds. We show that the power spe ctra due to these kinds of seed perturbations are determined by five a nalytic functions, which we determine numerically for a special exampl e. We put forward the view that, even if recent work disfavors the mod els with cosmic strings and global O(4) texture, causal scaling seed p erturbations merit a more thorough and general analysis, which we init iate in this paper.
