Detection of localized structures from multispacecraft data: Adaptive correlation function

Abstract : When several spacecraft pass at different distances from a localized structure like a field-aligned current tube, the corresponding magnetic signatures recorded on each spacecraft generally show different timescales, due to the different ``viewpoints'' of the spacecraft. For this reason, it is impossible to identify the presence of a unique structure from these signatures by using the classical correlation functions. In this paper, we present an ``adaptive correlation function'' which is a new analysis tool allowing to look for such ``correlations'' whatever the dilation factor is between two signals.
