- Description:
- Ion data from the Plasma Composition Experiment on ISEE-1 consist of a combination of (a) velocity moments for the four principal magnetospheric ion species H+, He++, He+, and O+, calculated in two different ways (using two different sets of assumptions) and covering the 0.01-0.1 and 0.1-16 keV/e energy ranges, (b) energy-angle spectra for the same four ions plus O++, covering the 0.01-17.9 keV/e range, and (c) mass spectra (<1 amu/e to about 150 amu/e) for four energy ranges, all derived once per each complete energy-mass scan cycle of the instrument, or once each 1- to 20-minute interval, depending on mode of operation, as well as (d) "total ion" moments, derived once per energy scan and assuming total count rate is due to H+ ions (0.1-16 keV).

- Description:
- 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.
