The table contains the timetags and average output amplitude in units
of nano-Tesla of a 1-to-10 Hz bandpass filter for a single magnetometer
axis selected by command. The sampling rate is 1/s. The table contains
data from MAG LAC packets generated on a given day with one LAC sample
given per row.
The TIME_TAG corresponds to the center time of the one-second interval
used to calculate the LAC value. START_TIME and STOP_TIME correspond to
the TIME_TAG values of the first row and last row (respectively) in the
table.

This product, MAGCALLAC12349_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.

A derived value for the time tag associated
with the data values in each record.
The derived value is created by the following formula:
MET + 0.05 * delta_ts + 0.5 + (dt_sample)*(i-1)*(num_samples/num_AC).
MET is the mission elapsed time for the entire science packet.
delta_ts is the time in seconds between the MET and the first sample
in the science packet.
dt_sample is the time between samples in seconds and is given by
dt_sample = 1/sample_rate where sample_rate is the reported sample
rate in samples per second.
num_samples is number of magnetometer samples.
num_AC is the number of logAC values.
i is the incremental counter for each of the logAC values. i=1 is the
first logAC value in the science packet.
