THEMIS Level 1 STATE file info:

The L1 STATE files contain the following data, sampled at one-minute intervals: probe position and velocity in GEI, GSE, and GSM coordinates; flags to indicate regions of interest and maneuver status; RA and declination of spin axis; spin period and spin phase; spin model parameters for high-precision interpolation of spin phase between one-minute data points. Version number indicates data source as follows: V00: predicted ephemeris and attitude, no spin period or spin phase; V01: predicted ephemeris and attitude, spin period and spin phase derived from probe telemetry; V02: predicted attitude, definitive ephemeris from magnetometer and Doppler tracking data; V03: corrected attitude and spin phase derived from fully calibrated magnetometer data.
