2 ISEE-1 Ion Plots ivo://nasa.gsfc.nssdc/SPMS-00237 NASA Dr. Kirk D. Borne Dr. Edwin J. Grayzeck Edwin.J.Grayzeck@nasa.gov solar wind space plasmas ion composition heliophysics magnetophysics mass spectra These hardcopy plots were provided as a supplement to the digital data from the Plasma Composition Experiment (NSSDC data set 77-102A-12I). A subset of the data in the digital data files is plotted in graphical form in a series of booklets, one booklet for each month of data. There are two pages of graphs for each day, and each page has a stack of 7 panels showing the variation of different parameters during the course of a 12-hour Universal Time interval. Panel 1 (top panel) shows densities of He++, He+, and O+ ions, and the "total" ion density (per cubic meter); Panel 2 shows He++/H+ density ratio; Panel 3 shows ion "thermal" energy (eV); Panel 4 shows "thermal" energy density multiplied by 2/3 along with the magnetic pressure (eV/m^3) and field strength (nT); Panel 5 shows ion drift speed (meters/sec) in the GSE X-Y plane; Panel 6 shows magnetic field elevation angle (degrees) relative to the GSE X-Y plane; Panel 7 shows ion drift angle and the magnetic longitude angle. http://nssdc.gsfc.nasa.gov/database/MasterCatalog?ds=SPMS-00237 Archive University Research
