Short summary
Short summary
In this paper, we summarize the difficulties that Sfe detection presents and explain a line of work we initiated to overcome these difficulties with the goal of achieving a system capable of performing automatic detection. Some properties of Sfe, including spherical symmetry around the vortex and different time durations between Sfe and other natural variations, were used to construct an index allowing us to detect Sfe.
