An automated algorithm has been used for SLAMS identification followed by a manual verification process to remove bow shock oscillations and other false detections. SLAMS have been defined to have an amplitude of at least two times the background magnetic field.  More details on the creation of the database are given in the following publication: Bergman, S., Karlsson, T., Wong Chan, T.
