The Cassini Radio and Plasma Wave Science (RPWS) raw complete data set includes all RPWS telemetry data for the entire Cassini mission. This data set includes raw telemetry values for each frequency channel for each sensor for all times during the mission including the two Venus flybys, the Earth flyby, the Jupiter flyby, interplanetary cruise, and the entire Saturn tour. Data for this data set are acquired from the RPWS Low Frequency Receiver (LFR), Medium Frequency Receiver (MFR), Medium Frequency Digital Receiver (MFDR) (which can be used to replace MFR band 2 data), High Frequency Receiver (HFR), Sounder, and Langmuir Probe (LP). Data are decompressed and internal receiver minipackets are unsegmented. This data set is intended to preserve the telemetry data and is to be used only as a last resort. Other RPWS archived data sets are designed to be complete and more easily used. Browse data sets associated with the other data sets provide a graphical search of the data included in this data set. This data set should be the last used by a user of any of the RPWS archive as it is in the least user-friendly form. Parameters ========== This data set includes all measurements from each sensor, frequency channel, and time step for which data were acquired by the RPWS. Processing ========== Data in this data set were processed by the use of a number of software programs which assemble segmented mini-packets in the raw telemetry packets into complete sets and de-compress the data that were compressed by one of a number of compression algorithms by the RPWS flight software onboard. Information included in the Software Users Guide included in the DOCUMENT directory on this volume provides information necessary to extract and use these data. Data ==== The data included in this data set are the complete set of RPWS telemetry. Ancillary Data ============== Ancillary data included with this data set collection include a series of files that describe the modes of the RPWS as a function of time and provide a time- ordered listing of Instrument Expanded Block (IEB) trigger commands (the mode by which the RPWS is reconfigured). Also a detailed description of each of the modes (or IEBs) is provided. Other data which are ancillary to this data set but which are archived separately from this collection are the Navigation and Ancillary Information Facility's SPICE kernels describing the position and attitude of Cassini and various solar system bodies as a function of time. Coordinate System ================= The data in this data set are measurements of wave electric and magnetic fields measured by the RPWS electric and magnetic sensors. These fields are presented as detected by the sensors and are not rotated into any other coordinate system. If desired the SPICE kernels can be used with the SPICE toolkit to convert from the spacecraft frame to virtually any frame which may be of use in analyzing these data. However, for many purposes, the wave amplitudes are extremely useful and may be entirely adequate with no coordinate transformations at all. Software ======== No software is provided to be used with this data set. Media/Format ============ These data are supplied to the Planetary Data System on DVD-R media using formats and standards of the PDS for such media.
