SMALL-SCALE MAGNETIC FLUX ROPE DATABASE


This is a small-scale magnetic flux rope database. The flux rope events in this database are detected by an automated program based on Grad-Shafranov reconstruction algorithm. The data used in detecting algorithm is from two spacecraft. The maximum detection window is 361 minutes, and the minimum duration threshold is 9 minutes for the WIND spacecraft. These parameters are 2165 minutes (36 hours) and 9 minutes for the ACE spacecraft. The detailed technical procedures with control flow and data flow can be found in this [flowchart].
