In this work we present a partially new method to analyze fluctuations whichare induced by causal scaling seeds. We show that the power spectra due to thiskind of seed perturbations are determined by five analytic functions, which wedetermine numerically for a special example. We put forward the view that, evenif recent work disfavors the models with cosmic strings and global O(4)texture, causal scaling seed perturbations merit a more thorough and generalanalysis, which we initiate in this paper.
