 Time Table generated by AMDA @ CDPP;Description: FTE list from Cluster 3 data. From \"A new multivariate time series data analysis technique: Automated detection of flux transfer events using Cluster data\" by Karimabadi et al., JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 114, A06216, doi:10.1029/2009JA014202, 2009 http://www.agu.org/journals/ja/ja0906/2009JA014202/The list is available as Auxiliary material \"Data Set S3\"Transformation into AMDA Time Table by V. Genot, CESR, Toulouse, France 29/06/2009 : - millisec have been omitted - the original event corresponds to the StartTime of the Time Table - if StopTime-StartTime = 1 sec then the event is a magnetosheath FTE - if StopTime-StartTime = 2 sec then the event is a magnetospheric FTE;Source: Upload Time Table;Creation Date :  2009-07-01 17:16:46 shared by Vincent Genot on 2009-11-24 18:52:50;</description>
