description
The table contains the timetags and 3-axis samples of the Low Voltage Power Supply (LVPS) as well as instrument parameters. The sample rate is commandable and can vary. The table contains data from MAG Status Packets generated on a given day. START_TIME and STOP_TIME correspond to the TIME_TAG values of the first row and last row (respectively) in the table.
