MAG will contribute to our understanding of the acceleration and transport of charged particles in the heliosphere, the dynamics of interplanetary shocks, and provide real time space weather measurements via the I-AliRT service. MAG design, assembly, operations, and calibration are led by Imperial College London. See https://imap.princeton.edu/spacecraft/instruments/magnetometer-mag for more details. <_Description>Source: Master/CDFglobalAttributes/TEXT Users should acknowledge the sources of data used in all publications, presentations, and reports using an appropriate DOI.
