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 (GS) reconstruction algorithm. The detailed technical procedures with control flow and data flow can be found in this [flowchart]. The comprehensive tools for the investigation of magnetic flux ropes including the extended GS-based detection and GS-type reconstruction are now available at GitHub or PyHC.
