– Superposed epoch analysis – Correlations (linear and entropy based) – Cluster analysis – Pattern definition and search
A(t+1d) Kp(t-8*24h) Kp(t) ΣKp(t-8d) ΣKp(t)
Mutual information between average ΣKp and ESD anomaly data
Mutual information between ΣKp and ESD anomaly data
– communicate over port 2001 => Firewall problems. – use of RMI for data access => RMI might be a problem on specific OS.
– Merged MAG and SWEPAM data – 64 second resolution
