Pagination or Media Count:
The author discusses a procedure whereby Sudden Phase Anomalies SPA can be classified as Major Events, Significant Events, or Minor Events. Also, by determining the path responsiveness of a path at any given time, Normalization factors can be applied to an observed Event to determine itsabsolute importance, or its relative importance when compared to a standard Event. The report contains the procedures necessary to determine the path responsiveness and normalization factors for any given VLF path. Standardized event categories are established for operational use, and equations are presented to define event categories on any SPA circuit. Author
