We approach the problem from a threefold perspective: a direct least-squares approach, an approach based on truncated Fourier series, and an approach using low-dimensional measures of the RAO. We give a few recommendations for possible further investigations. date: 2012 citation: Bonaschi, G. A. and Filatova, O. and Mercuri, C. and Muntean, A. and Peletier, M.
