Registration (Deadline: Jan. 20 2021)The issue with PWE/EFD Spin-fit L2 data
We found a serious problem with the EFD-Level2 spinfit data (from v01_01 to v04_01). The corrected data (v05_01) has already been released. Please check the data version used in your research.
The error occasionally makes the amplitude and direction of the electric field vector different from the actual values
