VG2 JUP PLS PLASMA DERIVED ION MOMENTS 96.0 SEC V1.0
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 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. Data format: column 1 is time (yyyy-mm-ddThh:mm:ss.sssZ), column 2 is the moment density in cm^-3. Each row has format (a24, 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.
