Processing  Comments
2010-04-30:  Estimated First release.
2010-07-22:  Reprocessed full mission for EFI, ESA, FGM, FIT, MOM, and SCM; changed all L2 time formats to f12.8 (from e13.6, e19.12, and f12.2 in various files) and added solarwind mode flags to ESA and MOM files. Also implemented new calibration data for FGM.
2012-09-05:  Reprocessed EFI L2 files for probes, A, D, E, after 2010-12-01, to correct a small timing error in 8 ksps AC-coupled mode.
2017-04-18 to 2017-05-04:   Reprocessed FGM, FIT, MOM, ESA, SST and EFI L2 files for all probes for the full mission with new magnetic field calibration data.
