Revised versions of these data sets (PVO-V-OMAG-3--SCCOORDS-HIRES-V2.0, PVO-V-OMAG-4--SCCOORDS-24SEC-V2.0, PVO-V-OEFD-4--EFIELD-24SEC-V2.0, PVO-V-OEFD-3--EFIELD-HIRES-V2.0) were released in 2022 and 2023. This is the first version of these data in PDS4. The metadata have been migrated to PDS4. The data are the same as those in the 2022 and 2023 releases. This data file was created from the binary flatfile PVO_OMAG_OEFD_INST_ORB2116.FFD For these ASCII data files, some of the data values were set to the flag value (9999.99) when the data value was less than -1000.0 or greater than 1000.0. The original, unaltered data values are available in the binary data files. 1984-09-20T21:51:32.114Z 1984-09-20T21:51:32.114Z Engineering Calibrated Pioneer Venus (PV) Mission urn:nasa:pds:context:investigation:mission.pioneer_venus data_to_investigation Pioneer Venus Orbiter (PVO) Host urn:nasa:pds:context:instrument_host:spacecraft.pvo is_instrument_host Orbiter Fluxgate Magnetometer (OMAG) Instrument urn:nasa:pds:context:instrument:pvo.omag is_instrument Venus Planet urn:nasa:pds:context:target:planet.venus data_to_target Solar Wind Plasma Stream urn:nasa:pds:context:target:plasma_stream.solar_wind data_to_target Venus Orbital Operations 2116 2116 urn:nasa:pds:pvo-omag-cal:data-anc-inststat-bin:2116::1.0 data_to_calibrated_product Data which had a value greater than 1000. nT or less than -1000. nT have been set to the flag value. In some cases a spacecraft coordinates B-field component could have been calculated from the other components and the field magnitude, but was not done in this version of the data. The original large data values are included in the original binary data files.

This is the first version of this product converted to PDS4. The DOI provided references the PDS3 source data set.
