description
The table contains the timetags, spacecraft position, and 3-axis calibrated samples of the magnetic field in J2000 coordinates in units of nano-Tesla. The sampling rate is commandable and can vary. The table contains data from MAG science packets generated on a given day with one vector sample given per row. START_TIME and STOP_TIME correspond to the TIME_TAG values of the first row and last row in the table,respectively.

description
This product, MAGJ2KSCI09155_V08.TAB, was originally released in 2015 as part of the PDS3 MESS-E/V/H/SW-MAG-3-CDR-CALIBRATED-V1.0 dataset. The metadata have been migrated to PDS4. The data themselves are unchanged.

description
A derived value for the timetag associated with the x,y,z sample in each record. The derived value is created by the following formula: MET + 0.05 * delta_ts + (dt_sample)*(I-1) - latency. MET is the mission elapsed time for the entire science packet. delta_ts is the delta time in seconds between the MET and the first sample in the downloaded science packet. dt_sample is the time between samples in seconds and given by dt_sample = 1/sample_rate where sample_rate is the reported sample rate in samples per second. I is the incremental counter for each data sample in the science packet. I=1 is the first sample in the packet. Latency is the sample rate-dependent delay of the time stamp recording relative to the actual time of observation.
