Overall¶

The dataset is divided into three main parts: 3D magnetic field data file , sample label file and database archive file.

1 3D magnetic field data file¶

is divided into two parts: summary information and specific data information.

• summary information including
  • Raw data header information
  • Information generated in the 3D magnetic field extrapolation
• Specific files include
  • Raw files
  • Preprocessing files
  • 3D magnetic field product files
  • Visualization files
