description
These data were updated to shift the ephemeris data (pos_sc_mso), and magnetometer data (magf) to use center time rather than start time, correct an error introduced into the calculation of magf a couple of years ago, and a 20% change in absolute geometric factor for the STATIC sensor based on cross calibrations with LPW. More information about these updates is provided in the collection and bundle labels.
