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.

Files thx_l2_fit_yyyymmdd_v01.cdf (where x = a,b,c,d or e):

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.
