Introduction: The folder "orbit_data" in every folder named by the CIR epoch time contains the position information of the Beida Image Electron Spectrometer (BD-IES) onboard a Chinese inclined geosynchronous orbit (IGSO) navigation satellite, from 3 days before the interface to 5 days after the CIR interface, with time corresponding to the files in "IES_data". Please check our website: http://ies.pku-space.cn/ for further overall information of BD-IES and contact the member of the BD-IES team before you use the data products. If you use these data products, we would appreciate an acknowledgement of the source. The preferred acknowledgement is: “The BD-IES team at Peking University” rather than any individual’s name. Please feel free to contact to Dr. Zong (qgzong@pku.edu.cn) or Dr. Zou (hongzou@pku.edu.cn) if you have questions or comments about the data products. Please cite the paper about the BD-IES instrument if the BD-IES data be used (Zou H, Ye Y G, Zong Q G, et al. Imaging energetic electron spectrometer onboard a Chinese navigation satellite in the inclined GEO orbit. Sci China Tech Sci, 2018, 61, https://doi.org/10.1007/s11431-018-9321-7). Description of the data products: The positions of BD-IES in GEO coordinates, GSE coordinates and GSM coordinates, with the L value using dipole model, magnetic latitude and magnetic local time are provided in the data product. The corresponding time (UTC) of each line can be obtained from the corresponding electron flux observation file in "IES_data". Following is the detailed description of the formats of the data products. Structure of the data product file: Column 1-3: X,Y,Z in GEO coordinates in Re (Re=6400 km); Column 4-6: X,Y,Z in GSE coordinates in Re (Re=6400 km); Column 7-9: X,Y,Z in GSM coordinates in Re (Re=6400 km); Column 10: L value Column 11: MagLat in rad Column 12: MLT in hour
