Abstract

This paper analyses the effects of random noise in determining errors and confidence levels for galaxy redshifts obtained by cross-correlation techniques. The main finding is that confidence levels have previously been overestimated, and errors inaccurately calculated in certain applications. New formul\ae\ are presented.

Keywords

cosmological redshift galaxy clustering and large-scale structure signal processing and noise analysis
