inboard and outfield fields in cartesian payload coordinates (bpl) to remove
the ambient field.

Mars Global Surveyor MAG/ER Geometry Collection
===============================================
This collection contains orbit summary information for the Mars Global Surveyor Low
Resolution and Omnidirectional Pre-mapping and Mapping Mission Phases.
This is a PDS4 archive of the following PDS3 data sets:
MGS-M-ER-3-MAP1/OMNIDIR-FLUX-V1.0 (https://doi.org/10.17189/1519748),
MGS-M-ER-3-PREMAP/OMNIDIR-FLUX-V1.0 (https://doi.org/10.17189/1519749),
MGS-M-ER-4-MAP1/ANGULAR-FLUX-V1.0 (https://doi.org/10.17189/1519750),
MGS-M-ER-5-FIELD-MAP-V1.0 (https://doi.org/10.17189/1519751),
MGS-M-MAG-3-MAP1/FULLWORD-RES-MAG-V1.0 (https://doi.org/10.17189/1519752),
MGS-M-MAG-3-MAPPING-HIGHRES-V1.0 (https://doi.org/10.17189/1519753),
MGS-M-MAG-3-PREMAP/FULLWORD-RES-MAG-V1.0 (https://doi.org/10.17189/1519754),
MGS-M-MAG-3-PREMAPPING-HIGHRES-V1.0 (https://doi.org/10.17189/1519755).
These collections were originally archived under PDS3 in the following volumes:
MGS_ER_ANGULAR, MGS_ER_MARS_MAP, MGS_MAG_HIGH_RES.
Under the PDS3 standard all archives were self contained and could in principle be
stored in a single file system (disk, CD-ROM, etc.). PDS4 takes advantage of the
network capabilities that allow archives to be distributed. As a result, some of
the documents and metadata previously stored in the PDS3 catalog files are no longer
maintained locally, but are maintained in a central repository. Those files are
referenced by unique PDS logical identifiers that are included in the document
collection inventory.
