Data Set Overview

The Juno Waves EDR complete data set includes all Waves science and housekeeping data for the entire Juno mission. This data set consists of reformatted, uncalibrated, spectra and waveforms as well as unaltered housekeeping packets. The reformatting operation re-assembles measurements which were too long to fit with in a single transmission unit to the Juno flight data system as well as decompressing data that were transmitted in compressed form. The data for this set were acquired from the Waves Low Frequency Receiver (LFR), High Frequency Receivers (HFR-44, HFR-45), as well as the Digital Signal Processor's housekeeping output. This data set is intended to preserve the uncalibrated instrument packets and is to be used only as a last resort. Other Waves archived data sets are designed to be complete and more easily used. Browse images associated with the other data sets provide a graphical search of the data included in this data set. The primary usefulness of these data lay in preserving the inputs to higher level calibrated data sets so that such sets may be regenerated in the event that better calibrations become available or in the event that mistakes are uncovered in the data processing pipelines. In either event the Waves instrument team is intended as the user of these data, *not* the wider scientific community.


The fundamental unit of this data set is a Waves packet. In the case of science packets, each packet contains a single measurement along with information required to calibrate the measurement and determine when it was collected. Actually producing calibrated data from these raw packets requires detailed knowledge of the Waves instrument. Housekeeping packets are also included as these contain fine timing information.


The data included in this data set were processed by the EDR processing pipeline as described in section 3.3 of the VOLSIS document found under the DOCUMENTS sub-directory. In short, this pipeline consists of programs which reassemble fragmented packets, decompress packets and check for CRC errors.


Products in this data set are simply described as PDS FILE objects with minimal detached labels as no more specific PDS objects exist to define a file consisting of variable length packets. Appendix C of the VOLSIS outlines the data format of these raw packets and the WAVES_PACKETS document, contained in the DOCUMENT directory, provides detailed information.

Ancillary Data

This data set is complete, though the generation of higher level calibrated data from this raw data set requires the following additional information: 1. Navigation and Ancillary Information Facility's SPICE toolkit and Juno mission SPICE kernels. 2. Calibration tables supplied on this volume by the Waves instrument team

Coordinate Systems

As these are raw data they are recorded in the frame of the electric and magnetic sensors and are not rotated into any other coordinate system. The WAVES_INST.CAT catalog file, located in this directory, contains a description of the detectors' orientation with respect to the Juno spacecraft coordinate frame.


No software is provided to view, interpret, or convert this data set.


This data set is provided to the Planetary Data System electronically as part of a volume level 'tarball' file, though the standards for file names, directory names and path lengths follow the guidelines provided in the 'Planetary Data System Standards Reference', version 3.8, under section 10.1.3, 'Specification for Files Delivered Electronically'. The 'tarball' file contains all files for a release of this volume in a single GNU Tar file that has then been compressed via the GNU gzip utility. The tar file preserves the relative directory path for each file so when unpacked the original volume directory structure is recreated. See Section 4 of the VOLSIS for more details on the data transfer methods.
