END_OBJECT = TEXT END This directory contains the Voyager 1 PLS 96 second res. electron and ion browse and fit data and in the solar wind and Saturn's magnetosphere during the SATURN encounter period of 1980-11-11 and 1980-11-21. The data are averaged to 96 second res. and stored in 7 ASCII tables, each accompanied by a PDS label file (.LBL) which describes properties of the data file. The PLS cup information is also provided in an ASCII file (PLS_CUP.TAB) along with its PDS label file. The data file details are described as the following: ------------------------------------------------------------------------ File Name Data Coverage File Contents ------------------------------------------------------------------------ ELE_FBR.TAB 1980-11-12 to 1980-11-13 electron browse ELE_FIT.TAB 1980-11-12 to 1980-11-13 electron fit ION_FBR.TAB 1980-11-12 to 1980-11-13 ion browse ION_FIT.TAB 1980-11-12 to 1980-11-13 ion fit ION_MOM.TAB 1980-11-12 to 1980-11-13 ion moment ION_SHEATH.TAB 1980-11-11 to 1980-11-12 ion magnetosheath ION_WIND.TAB 1980-11-11 to 1980-11-21 ion solar wind PLS_CUP.TAB 1980-11-12 to 1980-11-13 PLS cup information Additional information on this data set is available in the following files: file contents /CATALOG/PLSINST.CAT CRS instrument description /CATALOG/VG1_PLSEBDS.CAT electron browse data set description /CATALOG/VG1_PLSEFDS.CAT electron fit data set description /CATALOG/VG1_PLSIBDS.CAT ion browse data set description /CATALOG/VG1_PLSIFDS.CAT ion fit data set description /CATALOG/VG1_PLSIMDS.CAT ion moment data set description /CATALOG/VG1_PLSIWBDS.CAT ion solar wind browse data set description /CATALOG/VG1_PLSIWDS.CAT ion solar wind data set description /CATALOG/PERSON.CAT personnel information /CATALOG/REF.CAT key reference description /DOCUMENT/PLS/PLSDATA.ASC ASCII and HTML versions of the NSSDC's Data and PLSDATA.HTM instrument description document for this data set [NSSDCCRS1979] /DOCUMENT/PLS/PLSINST.ASC ASCII and HTML versions of the CRS investigation and PLSINST.HTM description paper [STONEETAL1977] /-------------------------\ | ELE_FBR DATA | \-------------------------/ ===================================================== name type description ----------------------------------------------------- ctime float_8 vg1satplsebr.ctime fit_den float_4 vg1satplsebr.fit_den fit_temp float_4 vg1satplsebr.fit_temp mom_den float_4 vg1satplsebr.mom_den mom_temp float_4 vg1satplsebr.mom_temp /-------------------------\ | ELE_FIT DATA | \-------------------------/ ========================================================================= name type description ------------------------------------------------------------------------- time A24 time in the format yyyy-mm-ddThh:mm:ss.sssZ imax I2 points in spectrum ifly I1 flag value: 1 = encounter, 0 = cruise thbn 1PE9.3 angle between d cup normal and mag. field vector (radians) rne 1PE9.3 moment electron density (cnts/cm**3) rte 1PE9.3 moment electron temperature (eV) phisc 1PE9.3 spacecraft potential (V) rnc 1PE9.3 cold electron density (cnts/cm**3) sgnc 1PE9.3 std. dev. of cold electron density (rnc) (cnts/cm**3) rtc 1PE9.3 cold electron temperature (eV) sgtc 1PE9.3 std. dev. of cold electron temperature (rtc) (eV) chic 1PE9.3 chi squared of the cold fit rnh1 1PE9.3 first hot electron density (cnts/cm**3) sgnh1 1PE9.3 std. dev. of first hot electron dens.
