Fig. 4

Initial speed and longitudinal dependence of the arrival-time error. a Relationship between predicted arrival-time error and initial speed of the CMEs. Pearson’s CC (Rp), Spearman’s rank CC (Rs), and the P-value (P) are shown in the left top. b Relationship between predicted arrival-time error and longitude of CME location. Colors indicate CMEs with initial speeds derived from CACTus (blue), the LASCO catalog (red), and the best fit to IPS data (black)
