This data set includes calibrated 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) and High Frequency Receiver (HFR). Data are presented in a set of tables organized so as to have fixed-length records for ease in data handling. This data set is intended to be the most comprehensive and complete data set included in the Cassini RPWS archive. A browse data set is included with these data which provides for a graphical search of the data using a series of thumbnail and full-sized spectrograms which lead the user to the particular data file(s) of interest. This data set should be among the first used by a user of any of the RPWS archive as it will lead one to information required to search for more detailed or highly specialized products.

This value ranges from 64 seconds per cycle during cruise phase to as low as 8 seconds. In Saturn orbit, 32 seconds is the slowest cycle typically used.

Other SCET SCET The standard JPL spacecraft event time description: yyyy-doyThh:mm, seconds and milliseconds are assumed zero. This is half of the SCLK/SCET pair produce by the SPICE kernel for the beginning of each day. Temporal SCLK SCLK The standard JPL spacecraft clock time description: ssssssssss.fff. This is half of the SCLK/SCET pair produce by the SPICE kernel for the beginning of each day. Temporal SCLK_SECOND SCLK_SECOND Spacecraft clock counter increments each second, beginning at approximately 1958-01-01T00:00:00Z. Temporal SCLK_PARTITION SCLK_PARTITION Spacecraft clock partition. A value of ZERO or ONE indicates the first partition (i.e. the spacecraft clock has not been reset). Temporal SCLK_FINE SCLK_FINE Spacecraft clock modulo 256 counter increments 256 times per second. Since the RTI increments from 0 through 7 in this same interval, SCLK_FINE / 32 yields the RTI count. For RPWS, SCLK_FINE is maintained within the instrument to an accuracy of one RTI period. Time tags should occur only with the following values for SCLK_FINE : 0, 32, 64, 96, 128, 160, 192, and 224 Temporal SCET_DAY SCET_DAY Spacecraft event time days since 1958-01-01T00:00:00Z Temporal SCET_MILLISECOND SCET_MILLISECOND Spacecraft event time millisecond of day allowing for up to two leap seconds.
