Title: Covariance Matrix for Helicity Couplings

In this paper, the helicity couplings at Q 2 = 0 for excited baryonic states have been determined in the past, but no information is available regarding their correlations that are relevant for comparison to theory. We present here our calculation of such correlations between the helicity couplings. Finally, they contain information for quantitative comparisons with theoretical values, they can be used to quantify the impact of polarization observables, and can help design new experiments.
