Cassini CAPS Fitted Parameters

This data collection contains fits (both good and bad) that were found during R. J. Wilson et al's grant from NASA's Cassini Data Analysis Program (NNX12AG90G).
The Cassini CAPS plasma data used in the forward model plasma
parameter calculations given here came from volume
CO-E/J/S/SW-CAPS-2-UNCALIBRATED-V1.0 in the Planetary Data System (PDS).

plasma ions in Saturn’s magnetosphere utilizing a forward model,

The main limitation to using this data set is that the data are not
calibrated and every bit was taken for operational testing or high voltage
checkouts. We do not expect any one to use this dataset for science.

The co-ordinate system used in this study and for the fitted velocity vectors is Saturn de-Spun-Sun (SSS) where +z is the Saturn spin axis, +y is defined as the cross product ofthe +z with the Saturn-to-Sun vector, and +x is defined as the cross product of +y with +z.
