description

The table contains the timetags and 3-axis samples of the magnetic field. The sampling rate is commandable and can vary. The table contains data from MAG science packets generated on a given day; data from each packet will be stored as one row in the ASCII table. START_TIME and STOP_TIME correspond to the TIME_TAG values of the first row and last row (respectively) in the table.

description

This product, MAGSCI043520002_V1.TAB, was originally released in 2015 as part of the PDS3 MESS-E/V/H/SW-MAG-2-EDR-RAWDATA-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). 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.
