Bundle cassini-rpws-key_parameters Version 1.0 Cassini Orbiter Radio and Plasma Wave Science Cassini RPWS Key Parameters Planetary Plasma Interactions Discipline Node of the Planetary Data System #### Introduction This bundle provides calibrated electric and magnetic field spectral density measurements in reduced temporal and spectral resolution obtained by the Cassini Radio and Plasma Wave Science (RPWS) instruments over the entire mission. The full-resolution calibrated data from a number of different instrument sections sampling at varying cadences and spectral resolutions are rebinned by selecting the median amplitude value in a set of regular bins with ten frequency intervals per decade and time intervals covering integral minutes in spacecraft event time. Both electric wave spectra in units of volts squared per meter squared per hertz in the frequency range from one hertz to sixteen megahertz and magnetic wave spectra in units of nanotesla squared per hertz in the frequency range from one hertz to twelve point six kilohertz are presented for the entire mission, including the flybys of Venus, Earth, and Jupiter, the interplanetary cruise, and the entire Saturn tour. These rebinned summary data are presented in fixed-length text tables for ease of use and should serve as a convenient starting point for any investigations. Higher-resolution information is available in the more-complex cassini-rpws-low_rate_full_resolution bundle from which this data set is derived. Note the disclaimer below. Users of these data are encouraged to acknowledge both the PDS and the principle investigators of the instruments whose data are used in analysis in all publications. #### Related PDS Products Related Cassini RPWS data bundles include: - cassini-rpws-low_rate_full_resolution - A higher-resolution but more-complex data bundle from which this bundle is derived - cassini-rpws-waveform - A multi-antenna rapid sample waveform data bundle ideal for deriving wave propagation parameters, although with relatively sparse coverage - cassini-rpws-wideband - A single-antenna rapid sample waveform data bundle ideal for observing either time-domain waveforms or high-resolution frequency-domain spectra, although with relatively sparse coverage #### File Formats The data files in this bundle are all ASCII text. All data files are described by PDS labels following PDS4 specifications. The extensible markup language label files for the data have the same name as the data files they describe, but with the extension .lblx. Each label file is in the same directory as the file it describes. All plain text documents and data files are stream format files, with a carriage return (ASCII 13) and a line feed character (ASCII 10) at the end of the record. This allows the files to be read by MacOS, DOS, Windows, and UNIX/Linux operating systems. UNIX/Linux system users may see an unnecessary carriage return character (^M) at the end of each line. PDS label files however follow the common XML practice of using lines terminated with a line feed character (ASCII 10) only. ASCII TAB files are formatted with fixed-length records and fixed-width columns separated by white space for ease of use. The ASCII lblx label files contain descriptions of the fields of each data file in extensible markup language format. In this bundle, all data files share the same format. More information on the PDS4 labels used in this bundle can be found at: https://pds.nasa.gov/datastandards/documents/ #### Bundle Contents and Structure ``` [cassini-rpws-key_parameters] Root directory | |- bundle.lblx PDS4 label file describing the bundle as a whole |- readme_1.0.md Plain text describing bundle contents, organization, | and use (this file) | |- [browse] Contains browse images of plots of these data | | | |- collection_browse.lblx PDS4 label describing the browse collection | |- collection_browse.csv List of items in the browse collection | | | |- [yyyy] Subdirectories for each year yyyy of browse files | | | |- Tyyyyddd_f_KPB.lblx PDS4 label describing an individual browse | | plot image containing either magnetic (f=B) or | | electric (f=E) field spectra for year yyyy and day of | | year ddd. | |- Tyyyydd_f_KPB.PNG The plot image corresponding to the above | label, displaying a dynamic spectrogram consisting of | the averaged magnetic (f=B) or electric (f=E) field | spectra for year yyyy and day of year ddd, calibrated | as dB above background for a given frequency interval. | The electron cyclotron frequency derived from MAG data | is overplotted in white and trajectory parameters | are included with tick labels. | |- [data] Contains primary collection for this bundle | | | |- collection_data.lblx PDS4 label describing the data collection | |- collection_data.csv List of items in the data collection | | | |- [yyyy] Subdirectories for each year of data files | | | |- RPWS_KEY__yyyyddd_v.lblx PDS4 label describing an individual | | data file with yyyyddd the year and day of year | | and v the version number of the file | |- RPWS_KEY__yyyyddd_v.TAB The data files comprising the primary | archive products.
