The table contains the timetags and 3-axis calibrated samples of the
magnetic field in heliospheric RTN coordinates in units of nano-Tesla, Br,
Bt, Bn. The spacecraft position is identified by radial distance from the
Sun, latitude above the ecliptic plane, and azimuth with respect to the
Earth-Sun line in the ecliptic plane. 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.

This product, MAGRTNSCI12341_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 r,t,n 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.
