AB: Being a constellation of four spacecraft, Cluster allows to discriminate spatial structures and temporal variations and provides the tools to determine the local system of reference and spatial gradient estimation. Using four-point magnetic field measurements we calculate the magnetic field curl and curvature vectors within flow reversal regions. This technique allows to map the X-line position and investigate plasma properties and magnetic field structure near and within a reconnection region. In this paper we review attempts to apply the multi-point data analysis methods to survey the 3-D magnetic and electric field structure, ion properties and wave activity for several examples of flow reversals, detected by Cluster at geocentric distance of 19 $R_E$ in the magnetotail.
