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 As a result, some of the documents and metadata previously stored in the PDS3 catalog files are no longer maintained locally, but are maintained in a central repository.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. Errata ====== An errata file has been included in the document collection. Known and additional issues are and will be noted in this file. Contacts ======== This bundle was produced for the Planetary Data System (PDS) at the Planetary Plasma Interactions (PPI) node.
