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. spase://CNES/Person/Elena.Budnik DataProducer spase://SMWG/Repository/CNES/CDPP-AMDA Online Open http://amda.cdpp.eu NetCDF PSA * CORB_DV_257_03___T19_00345.BSP * RORB_DV_257_03___T19_00345.BSP * CATT_DV_145_02_______00216.BC * CATT_DV_257_03_______00344.BC * ROS_V32.TF spase://CNES/Instrument/CDPP-AMDA/Rosetta/Ephemeris Ephemeris 2014-01-01T00:01:07Z 2016-09-30T23:59:08Z PT60S xyz_cso ros_xyz_cso pos.bodyrc;instr.obsty km Cartesian CSO TimeSeries 3 x 1 ros_xyz_cso(0) y 2 ros_xyz_cso(1) z 3 ros_xyz_cso(2) Positional xyz_cseq ros_xyz_cseq pos.bodyrc;instr.obsty km TimeSeries 3 x 1 ros_xyz_cseq(0) y 2 ros_xyz_cseq(1) z 3 ros_xyz_cseq(2) Positional lat C-G_ck ros_lat_ck deg TimeSeries Positional lon C-G_ck ros_lon_ck deg TimeSeries Positional distance ros-C-G ros_cg_r km TimeSeries Positional
