These frames are defined as a two-vector style dynamic frames as follows: - The position of the sun relative to the body is the primary vector: the X axis points from the body to the sun. - The inertially referenced velocity of the sun relative to the body is the secondary vector: the Y axis is the component of this velocity vector orthogonal to the X axis. - The Z axis is X cross Y, completing the right-handed reference frame. - All vectors are geometric: no aberration corrections are used. * CSEQ The body-Centered Solar EQuatorial frames for the Rosetta primary target comet 67P/Churyumov-Gerasimenko and secondary target asteroid 21/LUTETIA are named '67P/C-G_CSEQ' and '21/LUTETIA_CSEQ'. These frames are defined as a two-vector style dynamic frames as follows: - +X axis is the position of the Sun relative to the body; it's the primary vector and points from the body to the Sun; - +Z axis is the component of the Sun's north pole of date orthogonal to the +X axis; - +Y axis completes the right-handed reference frame; - the origin of this frame is the body's center of mass. All the vectors are geometric: no aberration corrections are used. * C_G-CK C_G comet fixed frame (CK frame) A body-fixed frame is defined using standard body-fixed, CK-based frame formation rules: - +Z axis is toward the North pole; - +X axis is toward the prime meridian; - +Y axis completes the right hand frame; - the origin of this frame is at the center of the body. The orientation of this frame is computed by evaluating corresponding C_G comet attitudes kernels. </Description> <Contact> <PersonID>spase://CDPP/Person/Elena.Budnik</PersonID> <Role>DataProducer</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>PSA</ProviderName> <InstrumentID>spase://CDPP/Instrument/AMDA/Rosetta/Ephemeris</InstrumentID> <MeasurementType>Ephemeris</MeasurementType> <TemporalDescription> <TimeSpan> <StartDate>2014-01-01T00:01:07Z</StartDate> <StopDate>2016-09-30T23:59:08Z</StopDate> </TimeSpan> <Cadence>PT60S</Cadence> </TemporalDescription> <Parameter> <Name>xyz_cso</Name> <ParameterKey>ros_xyz_cso</ParameterKey> <Description/> <Ucd>pos.bodyrc;instr.obsty</Ucd> <Units>km</Units> <CoordinateSystem> <CoordinateRepresentation>Cartesian</CoordinateRepresentation> <CoordinateSystemName>CSO</CoordinateSystemName> </CoordinateSystem> <RenderingHints> <DisplayType>TimeSeries</DisplayType> </RenderingHints> <Structure> <Size>3</Size> <Element> <Name>x</Name> <Index>1</Index> <ParameterKey>ros_xyz_cso(0)</ParameterKey> </Element> <Element> <Name>y</Name> <Index>2</Index> <ParameterKey>ros_xyz_cso(1)</ParameterKey> </Element> <Element> <Name>z</Name> <Index>3</Index> <ParameterKey>ros_xyz_cso(2)</ParameterKey> </Element> </Structure> <Support> <SupportQuantity>Positional</SupportQuantity> </Support> </Parameter> <Parameter> <Name>xyz_cseq</Name> <ParameterKey>ros_xyz_cseq</ParameterKey> <Ucd>pos.bodyrc;instr.obsty</Ucd> <Units>km</Units> <RenderingHints> <DisplayType>TimeSeries</DisplayType> </RenderingHints> <Structure> <Size>3</Size> <Element> <Name>x</Name> <Index>1</Index> <ParameterKey>ros_xyz_cseq(0)</ParameterKey> </Element> <Element> <Name>y</Name> <Index>2</Index> <ParameterKey>ros_xyz_cseq(1)</ParameterKey> </Element> <Element> <Name>z</Name> <Index>3</Index> <ParameterKey>ros_xyz_cseq(2)</ParameterKey> </Element> </Structure> <Support> <SupportQuantity>Positional</SupportQuantity> </Support> </Parameter> <Parameter> <Name>lat C-G_ck</Name> <ParameterKey>ros_lat_ck</ParameterKey> <Ucd/> <Units>deg</Units> <RenderingHints> <DisplayType>TimeSeries</DisplayType> </RenderingHints> <Support> <SupportQuantity>Positional</SupportQuantity> </Support> </Parameter> <Parameter> <Name>lon C-G_ck</Name> <ParameterKey>ros_lon_ck</ParameterKey> <Ucd/> <Units>deg</Units> <RenderingHints> <DisplayType>TimeSeries</DisplayType> </RenderingHints> <Support> <SupportQuantity>Positional</SupportQuantity> </Support> </Parameter> <Parameter> <Name>distance ros-C-G</Name> <ParameterKey>ros_r</ParameterKey> <Ucd/> <Units>km</Units> <RenderingHints> <DisplayType>TimeSeries</DisplayType> </RenderingHints> <Support> <SupportQuantity>Positional</SupportQuantity> </Support> </Parameter> </NumericalData> </Spase>
