THIS DATA SET CONTAINS THE DERIVED VALUES FOR THE ELECTRON MOMENT DENSITY AND TEMPERATURE AT JUPITER IN THE PLS ENERGY RANGE (10-5950 EV) DURING THE VOYAGER 2 ENCOUNTER. ADJACENT LOW AND HIGH ENERGY ELECTRON MEASUREMENTS ARE COMBINED TO FORM A COMPOSITE SPECTRA WHICH IS USED FOR THE MOMENT CALCULATION. THE MOMENT CALCULATIONS ARE PERFORMED AS DESCRIBED IN SCUDDER ET AL. (1981). THESE ASSUME ISOTROPIC DISTRIBUTIONS AND CORRECT FOR POSITIVE SPACECRAFT CHARGE WHEN APPLICABLE AND INTERPOLATE ELECTRON SPECTRA BELOW THE 10 EV INSTRUMENT THRESHOLD BEFORE PERFORMING THE INTEGRATION OVER VELOCITY. DATA FORMAT: COLUMNS 1-6 ARE TIME (YEAR, DAY, HOUR, MIN, SEC, MSEC) COLUMN 7 IS THE MOMENT DENSITY IN CM-3, COLUMN 8 THE TEMPERATURE IN EV. EACH ROW HAS FORMAT (6I4, 2E12.3). VALUES OF 1.E32 INDICATE THAT THE PARAMETER COULD NOT BE OBTAINED FROM THE DATA USING THE STANDARD ANALYSIS TECHNIQUE. ADDITIONAL INFORMATION ABOUT THIS DATASET AND THE INSTRUMENT WHICH PRODUCED IT CAN BE FOUND ELSEWHERE IN THIS CATALOG. AN OVERVIEW OF THE DATA IN THIS DATA SET CAN BE FOUND IN SCUDDER ET AL. (1981) AND A COMPLETE INSTRUMENT DESCRIPTION CAN BE FOUND IN BRIDGE (1977).

This data set contains derived values of the electron density and moment temperature at Jupiter during the Voyager 2 encounter in the PLS voltage range (10-5950 eV/q). Adjacent low and high energy electron measurements are combined to form a composite spectra which is used for the moment calculation. These assume isotropic distributions and correct for positive spacecraft charge when applicable and interpolate electron spectra below the 10 eV instrument threshold before performing the integration over velocity. Data format: column 1 is time (yyyy-mm-ddThh:mm:ss.sssZ), column 2 is the moment density in cm^-3, column 3 the temperature in eV. Each row has format (a24, 2(1x,1pe9.2)). Values of -9.99e+10 indicate that the parameter could not be obtained from the data using the standard analysis technique. Additional information about this data set and the instrument which produced it can be found elsewhere in this catalog.

THIS DATA SET CONTAINS THE BEST ESTIMATES OF THE TOTAL ION DENSITY FROM VOYAGER 2 AT JUPITER IN THE PLS VOLTAGE RANGE (10-5950 EV/Q). IT IS CALCULATED USING THE METHOD OF MCNUTT ET AL. (1981) WHICH TO FIRST ORDER CONSISTS OF TAKING THE TOTAL MEASURED CURRENT AND DIVIDING BY THE COLLECTOR AREA AND PLASMA BULK VELOCITY. THIS METHOD IS ONLY ACCURATE FOR HIGH MACH NUMBER FLOWS DIRECTLY INTO THE DETECTOR, AND MAY RESULT IN UNDERESTIMATES OF THE TOTAL DENSITY OF A FACTOR OF 2 IN THE OUTER MAGNETOSPHERE. THUS ABSOLUTE DENSITIES SHOULD BE TREATED WITH CAUTION, BUT DENSITY VARIATIONS IN THE DATA SET CAN BE TRUSTED. THE LOW RESOLUTION MODE DENSITY IS USED AT ALL TIMES EXCEPT DAY 190 2100-2200 WHEN THE LARGER OF THE HIGH AND LOW RESOLUTION MODE DENSITIES IN A 96 SEC PERIOD IS USED. COROTATION IS ASSUMED INSIDE L=17.5, AND A CONSTANT VELOCITY COMPONENT OF 200 KM/S INTO THE D CUP IS USED OUTSIDE OF THIS. THESE ARE THE DENSITIES GIVEN IN THE MCNUTT ET AL. (1981) PAPER CORRECTED BY A FACTOR OF 1.209 (.9617) FOR DENSITIES OBTAINED FROM THE SIDE (MAIN) SENSOR. THIS CORRECTION IS DUE TO A BETTER CALCULATION OF THE EFFECTIVE AREA OF THE SENSORS. DATA FORMAT: COLUMNS 1-6 ARE TIME (YEAR, DAY, HOUR, MIN, SEC, MSEC) COLUMN 7 IS THE MOMENT DENSITY IN CM-3. EACH ROW HAS FORMAT (6I4, E12.3). VALUES OF 1.E32 INDICATE THAT THE PARAMETER COULD NOT BE OBTAINED FROM THE DATA USING THE STANDARD ANALYSIS TECHNIQUE.

THIS DATA SET CONTAINS ELECTRON PARAMETERS IN THE PLS ENERGY RANGE (10-5950 EV) AT SATURN DURING THE VOYAGER 2 ENCOUNTER. PARAMETERS ARE CALCULATED IN SEVERAL WAYS. TOTAL MOMENT DENSITY AND TEMPERATURE ARE GIVEN. EACH ELECTRON SPECTRUM IS ALSO FIT WITH A THERMAL COMPONENT AND 1-3 HOT COMPONENTS DEPENDING ON HOW MANY MAXWELLIANS ARE NEEDED TO FIT THE ENTIRE DISTRIBUTION. THE MOMENT DENSITY AND TEMPERATURE OF THE HOT COMPONENT IS CALCULATED AFTER THE THERMAL COMPONENT IS SUBTRACTED FROM THE SPECTRUM. THE CHI-SQUARE VALUE FOR EACH FIT IS GIVEN. THE SPACECRAFT CHARGE IS NOT CALCULATED CONSISTENTLY, AND MAY RESULT IN FACTOR OF 2-3 ERRORS IN THE THERMAL ELECTRON DENSITY. DATA IS UNRELIABLE INSIDE 6 RS AND IN THE OCCULTATION REGIONS. A COMPLETE DESCRIPTION OF THIS DATA SET IS IN SITTLER ET AL. (1983). DATA FORMAT: THE DATA SET IS IN ASC FORMAT AND CAN BE READ USING THE FOLLOWING FORTRAN STATEMENT:\n
