Automated range switching allows the instrument to maintain maximum digital resolution over a wide range of field strengths. The text of this instrument description has been abstracted from the instrument paper: Acuna, M. A., J. E. P. Connerney, P. Wasilewski, R. P. Lin, K. A. Anderson, C. W. Carlson, J. McFadden, D. W.

The development of the netCDF files was supported by the NASA Postdoctoral Program Fellowship awarded to Teresa Esman in 2022. The success of the MGS MAG project is owed to, among others, the people listed here: https://mars.nasa.gov/mgs/people/. Addtional information on the MAG dataset can be found at: https://mgs-mager.gsfc.nasa.gov/status.html. Documentation on MGS MAG data on the PDS has been maintained by J.E.P. Connerney, Mark Sharlow, D. Kazden, J. Springborn, and B. Semenov, among others. Teresa Esman, now a NPP Fellow at NASA Goddard Space Flight Center, compiled MGS MAG low resolution and high resolution data products, translated time to unix time, and performed the calculation and interpolation (to high resolution) of the altitude data product. <_Acknowledgement>Source: Master/CDFglobalAttributes/Acknowledgement <_Rights> SPDX Creative Commons Zero v1.0 Universal https://spdx.org/licenses/CC0-1.0.html https://spdx.org/licenses/ https://pds-ppi.igpp.ucla.edu/search/?sc=Mars%20Global%20Surveyor&i=MAG MGS MAG MGS MAG magnetic field .STS files from 1997-09-12 through 2006-11-02 are avalible at <_Note>Source: from all.xml/other_info/link Mars Global Surveyor MAG Data <_DOI>Source: https://github.com/rweigel/cdawmeta-spase/blob/main/DOI.json <_AccessInformation>Source: https://github.com/rweigel/cdawmeta-spase/blob/main/AccessInformation.json 1997-09-14T00:42:11Z 2006-11-02T23:23:43Z <_TemporalDescription>Generated from all.xml/@timerange_start and all.xml/@timerange_stop <_ObservedRegion>Source: https://github.com/rweigel/cdawmeta-spase/blob/main/ObservedRegion.json <_ProcessingLevel>Processing level is not available in the master file; it should be there instead of, say, https://github.com/rweigel/cdawmeta-spase/blob/main/ProcessingLevel.json spase://SMWG/Repository/NASA/GSFC/SPDF Online Open SPDF/CDAWeb.
