The data are provided in spacecraft coordinates. In one format, apoapsis B, the magnetometer can be commanded to return 3 vectors per minor frame. In most others it transmits one vector per minor frame. In one format, periapsis E, it has no words in a minor frame. At very low sampling rates at which time the sine wave due to spacecraft spin could not be resolved. The magnetometer values are despun, and averaged on board using a Walsh transform (square wave) in phase and in quadiatune with the sun.</Description> <Contact> <PersonID>spase://SMWG/Person/Raymond.J.Walker</PersonID> <Role>GeneralContact</Role> </Contact> </ResourceHeader> <AccessInformation> <RepositoryID>spase://SMWG/Repository/CDPP/AMDA</RepositoryID> <Availability>Online</Availability> <AccessRights>Open</AccessRights> <AccessURL> <URL>http://amda.cdpp.eu</URL> </AccessURL> <Format>NetCDF</Format> </AccessInformation> <ProviderName>PDS</ProviderName> <ProviderResourceName>PVO-V-OMAG-3--SCCOORDS-HIRES-V1.0</ProviderResourceName> <InstrumentID>spase://CDPP/Instrument/AMDA/PioneerVenusOrbiter/OMAG</InstrumentID> <MeasurementType>MagneticField</MeasurementType> <TemporalDescription> <TimeSpan> <StartDate>1978-12-05T07:20:18Z</StartDate> <StopDate>1988-10-14T14:00:10Z</StopDate> </TimeSpan> <Cadence>PT12S</Cadence> </TemporalDescription> <ObservedRegion>Venus</ObservedRegion> <Parameter> <Name>b_sc</Name> <ParameterKey>pvo_b_12s</ParameterKey> <Description>Magnetic field vector components in SpaceCraft coordinates</Description> <Ucd>phys.magField</Ucd> <Units>nT</Units> <RenderingHints> <DisplayType>TimeSeries</DisplayType> </RenderingHints> <Structure> <Size>3</Size> <Element> <Name>bx</Name> <Index>1</Index> <ParameterKey>pvo_b_12s(0)</ParameterKey> </Element> <Element> <Name>by</Name> <Index>2</Index> <ParameterKey>pvo_b_12s(1)</ParameterKey> </Element> <Element> <Name>bz</Name> <Index>3</Index> <ParameterKey>pvo_b_12s(2)</ParameterKey> </Element> </Structure> <Field> <Qualifier>Vector</Qualifier> <FieldQuantity>Magnetic</FieldQuantity> </Field> </Parameter> <Parameter> <Name>|b|</Name> <ParameterKey>pvo_bmag_12s</ParameterKey> <Description>Magnetic field magnitude</Description> <Ucd>phys.magField</Ucd> <Units>nT</Units> <RenderingHints> <DisplayType>TimeSeries</DisplayType> </RenderingHints> <Field> <Qualifier>Magnitude</Qualifier> <FieldQuantity>Magnetic</FieldQuantity> </Field> </Parameter> </NumericalData> </Spase>
