Fig. 7From: The 17 March 2015 storm: the associated magnetic flux rope structure and the storm developmentForm of response function we assumed to evaluate the effect of the solar wind electric field on the injection rate of ring current. The lengths of four phases (\( T_{\text{d}} \), \( T_{\text{r}} \), \( T_{\text{m}} \), \( T_{\text{f}} \)) determine the injection rateBack to article page
