                         to evaluate the properties of the magnetic cloud (MC) observed on 
                         19 22 March 2001. We used physical and mathematical approaches to 
                         analyze the time series of solar wind plasma and interplanetary 
                         magnetic field data. Two methods that are commonly used to derive 
                         the MC properties, the minimum variance analysis and the 
                         GradShafranov reconstruction, were applied to derive the 
                         properties of the MCs by fitting in situ measurements in the 
                         corresponding time intervals, as discussed in previous studies. 
                         Other methods developed by us (a travel time analysis of the 
                         interplanetary coronal mass ejection, spatio-temporal entropy, 
                         nonlinear fluctuation analysis, and wavelet analysis) are used as 
                         auxiliary tools to help identify whether the event consists of one 
                         or possibly two MCs. Our results suggest that the 19 22 March 2001 
                         event was composed by two MCs. Our results agree with those of 
                         other researchers who used various fitting methods and identified 
                         the solar origin of this event as two CMEs.",
