FIT Level 2 Data Processing History
This web page contains significant dates for changes in the software and mastercdfs that are used to create THEMIS Level 2 data files for the FIT (Fields Filter Bank) data. Dates for reprocessing of FIT L2 files are included.

| Processing | Comments | ||
| Date | |||
| 2007-06-15: | First release. | ||
| 2007-09-11: | Reprocessed all L2 files to clean out bad files. No change in FIT variables. | ||
| 2008-01-10: | Full L2 reprocessing. No changes in variables or file format. | ||
| 2008-04-18: | Full L2 reprocessing for TDAS version 4.00 QA. No changes in variables. | ||
| 2008-10-27: | Reprocessed FIT L2 to add software version number. | ||
| 2010-02-27: | Reprocessed ESA, MOM, FIT, and FGM L2 files, due to new FGM calibrations, and new V03 L1 STATE data. No changes in variables or file format. | ||
| 2010-04-21: | Reprocessed ESA, MOM, and FIT L2 files, due to new FGM calibrations, and new V03 L1 STATE data. No changes in variables or file format. | ||
| 2010-05-17: | Reprocessed THB (post 24-Jul-2009), THC (post 13-apr-2010) L2 files in response to filled data gaps from L0/L1 processing. | ||
| 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. | ||
| 2010-11-01: | Reprocessed FIT data post 2010-10-12 to account for use of e34 in EFS fits for probe B. | ||
| 2011-01-07: | Reprocessed full mission for ESA, FBK, FGM, FFT, FIT, MOM, SCM, and SST; to correct for data gaps at day boundaries caused by time clipping in load routines. | ||
| 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. | ||
| 2019-11-15: | Reprocessed All probe L2 files for THEMIS-A:Oct 6-12 2019;Oct 25-29 2019, THEMIS-D:Oct 26-27 2019,THEMIS-E:Oct 26-28 2019;June 21-22 2012, all but 2012 files due to power outage of October 2019. | ||
| 2023-06-05: | Set all THEMIS E L2 FGS data to fill post 2023-04-27, due to calibration offset anomaly. | ||
| 2023-07-12: | Reprocessed FGM and FIT L2 files for all probes, from 2022-10-30 on, with updated FGM calibration data. | ||
| 2023-08-14: | Reprocessed FGM and FIT L2 files for all probes, full mission up to 2022-10-30, to insure match between FGS data in both files, and match with calibrated L1 data. | ||
| 2023-09-08: | Reprocessed FGM and FIT L2 files for probe A, after 2023-04-29; for probe B, after 2022-11-01; for probe C, after 2022-08-01; for probe D, after 2022-12-02; for probe E, after 2022-12-01, with updated calibration data. | ||
| 2023-09-26: | Reprocessed FGM and FIT L2 files for probe C, after 2022-07-31, with corrected Bz offset. | ||
| 2023-11-06: | Reprocessed FGM and FIT L2 files for probe A, after 2023-07-19; for probe B, after 2023-03-01; for probe C, after 2022-07-01; for probe D, after 2023-07-15; for probe E, after 2023-03-01, with updated calibration data. | ||
| 2024-01-16: | Reprocessed FGM and FIT L2 files for all probes, after 2023-10-29, with updated calibration data. | ||
| 2024-03-25: | Reprocessed FGM and FIT L2 files for all probes, after 2023-12-31, with updated calibration data. | ||
| 2024-05-08: | Reprocessed FGM and FIT L2 files for all probes, THA and D after 2024-03-01, THB and C after 2023-09-01, and THE after 2023-04-24, with updated calibration data. |
