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 detailed technical procedures with control flow and data flow can be found in this [flowchart].
