This dataset contains the barycenter of the tetrahedron and positions of the spacecrafts relative to the barycenter. Positions are expressed in GSE and GSM coordinate systems. spase://CNES/Person/M.G.Henderson PrincipalInvestigator spase://CNES/Person/S.K.Morley PrincipalInvestigator MMS homepage at GSFC http://mms.gsfc.nasa.gov/ Science Data Center at LASP http://lasp.colorado.edu/mms/sdc/ mms1-orb-t89d spase://SMWG/Repository/CNES/CDPP-AMDA Online Open AMDA at CDPP amda.cdpp.eu NetCDF IRAP spase://CNES/Instrument/CDPP-AMDA/MMS1234/Ephemeris Ephemeris 2000-08-22T00:00:00Z 2019-01-14T15:58:00Z PT30S xyz_bary_gse mms1234_xyz_bary_gse Spacecraft barycenter position in GSE pos.earth;instr.obsty Re 6.4e6>m Cartesian GSE TimeSeries 3 x Component.I 1 mms1234_xyz_bary_gse(0) y Component.J 2 mms1234_xyz_bary_gse(1) z Component.K 3 mms1234_xyz_bary_gse(2) Positional xyz_bary_gsm mms1234_xyz_bary_gsm Spacecraft barycenter position in GSM pos.earth;instr.obsty Re 6.4e6>m Cartesian GSM TimeSeries 3 x Component.I 1 mms1234_xyz_bary_gsm(0) y Component.J 2 mms1234_xyz_bary_gsm(1) z Component.K 3 mms1234_xyz_bary_gsm(2) Positional separation mms1 gse mms1234_sep_mms1_gse MMS1 barycenter separation in GSE pos.earth;instr.obsty km 6.4e6>m Cartesian GSE TimeSeries 3 x Component.I 1 mms1234_sep_mms1_gse(0) y Component.J 2 mms1234_sep_mms1_gse(1) z Component.K 3 mms1234_sep_mms1_gse(2) Positional separation mms1 gsm mms1234_sep_mms1_gsm MMS1 barycenter separation in GSM pos.earth;instr.obsty km 6.4e6>m Cartesian GSM TimeSeries 3 x Component.I 1 mms1234_sep_mms1_gsm(0) y Component.J 2 mms1234_sep_mms1_gsm(1) z Component.K 3 mms1234_sep_mms1_gsm(2) Positional separation mms2 gse mms1234_sep_mms2_gse MMS2 barycenter separation in GSE pos.earth;instr.obsty km 6.4e6>m Cartesian GSE TimeSeries 3 x Component.I 1 mms1234_sep_mms2_gse(0) y Component.J 2 mms1234_sep_mms2_gse(1) z Component.K 3 mms1234_sep_mms2_gse(2) Positional separation mms2 gsm mms1234_sep_mms2_gsm MMS2 barycenter separation in GSM pos.earth;instr.obsty km 6.4e6>m Cartesian GSM TimeSeries 3 x Component.I 1 mms1234_sep_mms2_gsm(0) y Component.J 2 mms1234_sep_mms2_gsm(1) z Component.K 3 mms1234_sep_mms2_gsm(2) Positional separation mms3 gse mms1234_sep_mms3_gse MMS3 barycenter separation in GSE pos.earth;instr.obsty km 6.4e6>m Cartesian GSE TimeSeries 3 x Component.I 1 mms1234_sep_mms3_gse(0) y Component.J 2 mms1234_sep_mms3_gse(1) z Component.K 3 mms1234_sep_mms3_gse(2) Positional separation mms3 gsm mms1234_sep_mms3_gsm MMS3 barycenter separation in GSM pos.earth;instr.obsty km 6.4e6>m Cartesian GSM TimeSeries 3 x Component.I 1 mms1234_sep_mms3_gsm(0) y Component.J 2 mms1234_sep_mms3_gsm(1) z Component.K 3 mms1234_sep_mms3_gsm(2) Positional separation mms4 gse mms1234_sep_mms4_gse MMS4 barycenter separation in GSE pos.earth;instr.obsty km 6.4e6>m Cartesian GSE TimeSeries 3 x Component.I 1 mms1234_sep_mms4_gse(0) y Component.J 2 mms1234_sep_mms4_gse(1) z Component.K 3 mms1234_sep_mms4_gse(2) Positional separation mms4 gsm mms1234_sep_mms4_gsm MMS4 barycenter separation in GSM pos.earth;instr.obsty km 6.4e6>m Cartesian GSM TimeSeries 3 x Component.I 1 mms1234_sep_mms4_gsm(0) y Component.J 2 mms1234_sep_mms4_gsm(1) z Component.K 3 mms1234_sep_mms4_gsm(2) Positional
